If anxiety has started determining where you go, what you eat, how far you drive, this article is for you!

Maybe you take the longer route to work because you don’t want to drive on the highway. You go to the social event, but first you make sure someone you know will be there. A headache sends you online to check whether it could be something serious. Before a presentation, you rehearse what you’re going to say over and over because you’re afraid you’ll freeze or embarrass yourself.

These are all very different experiences, but anxiety can create a similar pattern in each of them. Something feels threatening, you find a way to reduce the anxiety, and you feel better… for a little while.

That relief is part of what makes anxiety so difficult to get out of. Your brain and nervous system pay attention to what you did right before you felt better. If taking the back roads lowered your anxiety, avoiding the highway starts to feel important. If Googling your symptoms gave you reassurance, you’re more likely to Google the next symptom or want to check again when the anxiety returns. If rehearsing a conversation ten times helped you feel more prepared, it becomes harder to walk into the next conversation without doing it.

Over time, these patterns can take up more and more space in your life in ways that are really not productive. Exposure-based therapy, including Exposure and Response Prevention (ERP), helps therapists and clients work directly with this cycle to start to break it.

What Is ERP or Exposure Therapy?

Exposure and Response Prevention, usually shortened to ERP, is a form of cognitive behavioral therapy. ERP is particularly well established in the treatment of obsessive-compulsive disorder (OCD), but exposure and response prevention-based strategies are also used when treating other anxiety-related problems, including panic, health anxiety, social anxiety, phobias, emetophobia (fear of vomiting), and fears that have led to significant avoidance and shrunk people’s worlds.

In therapy, exposure means intentionally approaching something that brings up anxiety or uncertainty. Response prevention means changing some of the things you typically do afterward to make yourself feel safer or get rid of the anxiety.

I think that second part is especially important because exposure therapy is sometimes reduced to the idea of “facing your fears.” There is more happening clinically than simply putting yourself in an uncomfortable situation.

We want to understand what your brain believes is dangerous, what you predict will happen, and how you respond when anxiety shows up. Then we can begin changing that pattern in a deliberate way to create the kind of change and relief you are seeking.

Why Avoidance Can Make Anxiety Stronger

Imagine that you’ve recently started feeling anxious on the highway. You’re approaching the entrance ramp one morning and notice your heart beating faster. You start thinking about what would happen if you became dizzy or had a panic attack while driving or, what if you had a heart-attack while driving. You decide to take the back roads instead (I have been there!)

Your anxiety comes down.

From your brain’s perspective, avoiding the highway appears to have worked. The next time you approach the highway, the urge to avoid it may be even stronger.

This is one of the frustrating things about anxiety. The strategies that help you feel better in the moment can sometimes strengthen the fear over time.

I see this frequently with health anxiety as well. Someone notices a sensation in her body and becomes worried that it could mean something serious. She searches the symptom online, reads several articles, checks the area of her body, and eventually finds information that reassures her and now she feels calmer and can get on with her day.

Then another sensation appears a few days later. Her brain already knows where to go for relief.

Checking again makes sense in that moment, especially when the fear feels real. But if this cycle happens repeatedly, the person has fewer opportunities to learn that she can notice a sensation, experience uncertainty about it, and continue with her day without immediately needing an answer.

A similar cycle can develop with emetophobia which is a fear of vomiting. Someone may notice a small sensation in her stomach and immediately begin monitoring whether she feels nauseated. She might avoid a restaurant because she worries the food could make her sick, check expiration dates repeatedly, or ask other people whether they feel okay after eating the same meal. Each precaution can bring some relief, which makes it tempting to rely on it again the next time the fear appears.

 One analogy I love to help explain this is to think of us humans as having a built in thermostat, it can go up high and then it will come back down on its own as the temperature changes naturally. But if we start to mess with it by doing something to artificially bring it back down, then it will stop working and start needing us to do the thing to get it to come back down. Until we start to break the cycle that is!

Avoidance Can Be Hard to Recognize

Some forms of avoidance are obvious. You stop flying. You won’t drive on the highway. You decline invitations because social situations make you anxious and you just never volunteer to give a staff training at work.

I have found that other forms are much harder to notice however.

You might still drive, but only when someone else is in the car. You go to the restaurant, but you need to sit somewhere that makes it easy to leave. You attend the party, but stay close to the person you came with. You’ve stopped Googling medical symptoms, but you regularly ask your spouse whether something looks concerning. You speak during the meeting, but only after rehearsing exactly what you’re going to say.

With emetophobia, avoidance can become especially easy to miss because some of the behaviors can very easily look like ordinary caution. A person might avoid certain foods, restaurants, alcohol, travel, amusement rides, or being around someone who was recently sick. She may carry medication “just in case,” monitor how her stomach feels throughout the day, or carefully track when and what she ate. She may start asking family members if they have been ill at all before gathering each visit (which can quickly start to aggravate others). 

In exposure work, we pay attention to these types of safety behaviors because they tell us something about what anxiety has taught you. Which is really what it all boils down to.

There is nothing inherently unhealthy about sitting near an exit, asking your spouse a question, checking whether food is safe to eat, or preparing before a meeting. Context matters. We become more interested in the behavior when you start to believe you need it in order to cope and when your life starts to shrink in ways that don’t align with your values.

If you can drive only when your partner comes with you, your brain doesn’t get much opportunity to discover what happens when you drive by yourself. If you always need reassurance after noticing a body sensation, you have fewer opportunities to experience uncertainty without immediately responding to it. If you always need to ask family members repeatedly “just checking if everyone in the house is well and has been well for the last week?” before continuing with gathering plans, your nervous system never learns to tolerate the uncertainty of trust. 

These details matter when we’re figuring out what is keeping an anxiety pattern going.

The Response Prevention Part of ERP

Response prevention is often where the deeper work happens.

Consider someone with health anxiety who notices a swollen lymph node and has the immediate thought, What if this is cancer?

Her anxiety rises quickly. She might Google swollen lymph nodes, feel the area repeatedly, compare one side of her neck to the other, ask her partner to check it, search Reddit for similar experiences, or ask an AI chatbot whether the symptom sounds concerning.

She may also reassure herself mentally: I’m young. I’m healthy. I just had bloodwork. I’m probably fine.

Each of these responses has the potential to bring the anxiety down temporarily. If you have not noticed, the KEY here is the word “temporarily”. 

In ERP, we start to break this cycle by altering the typical compulsion to immediately complete that usual sequence. She might notice the urge to check and wait before acting on it. She might allow the thought about cancer to remain unanswered instead of spending the next hour trying to prove that she’s okay.

That can apply to other fears too. Someone with emetophobia might practice noticing a normal stomach sensation without repeatedly checking whether it is getting worse, asking someone else if they think she looks sick, or immediately changing what she planned to eat that day.

That is difficult because anxiety is asking for certainty right now. Response Prevention gives us a structured way to practice tolerating some of that uncertainty.

With repetition, the person has new experiences to learn from. She begins discovering that an anxious thought doesn’t always require an investigation and that she is capable of having uncertainty without immediately resolving it.

What Exposure Therapy Can Look Like

Exposure therapy is individualized because the fears and behaviors maintaining anxiety are different from person to person.

Before beginning exposures, I want to understand the pattern. What situations trigger your anxiety? What do you think could happen? What do you avoid? How do you try to prevent the feared outcome? What do you do to bring your anxiety back down? We call these “safety behaviors”

Once we understand those pieces, we can develop exposures that make sense for you. We will often organize them from more manageable situations to ones that feel more challenging.

For someone with driving anxiety, that might include driving a familiar road alone and gradually working toward busier roads or highways.

For someone with social anxiety, it could mean contributing to a conversation without planning the sentence beforehand, asking a question during a meeting, or sending a text without rereading it repeatedly.

When someone has become afraid of the physical sensations associated with panic, we may use interoceptive exposure. This involves intentionally and safely bringing on certain sensations, such as a faster heartbeat or mild dizziness, so the person can practice experiencing them without immediately responding as though they signal danger.

With health anxiety, exposure work may involve reducing body checking, delaying reassurance seeking, or allowing a health-related question to remain unanswered.

For emetophobia, exposure work is carefully individualized and may involve gradually approaching avoided situations, words, images, foods, or physical sensations while reducing the safety behaviors that have developed around the fear. As with other forms of exposure, this is planned collaboratively rather than jumping straight to someone’s most feared situation.

The specific exercise matters, but what the person learns from it matters even more.

What If I Feel Anxious During an Exposure?

You probably will. And in most cases,the anxiety will go down over time. 

Often anxiety decreases while someone practices an exposure, and repeated experiences can make a situation feel much easier over time. There are also times when anxiety remains present for a while.

I don’t want clients measuring every exposure by whether they managed to get their anxiety down to zero. That can easily become another way of monitoring and controlling anxiety.

Instead, I’m interested in what you were able to do while anxiety was there.

Were you able to continue driving even though your heart was beating faster and had thoughts about crashing? Could you stay in the social situation while feeling awkward? Could you notice a physical sensation without immediately Googling it? Could you feel a little nauseated without immediately changing your plans or trying to determine whether you might throw up? Could you tolerate not knowing exactly what someone thought about you or if you offended them?

Those experiences give your brain different information.

You begin building confidence based on what you can handle rather than on how successfully you can prevent yourself from feeling anxious.

Learning to Tolerate Uncertainty

Uncertainty comes up constantly in anxiety treatment.

Health anxiety wants certainty that the test result will be normal. Social anxiety wants to know that nobody thought you sounded awkward or dumb. Driving anxiety wants reassurance that you won’t panic behind the wheel. Emetophobia wants to know that the food is safe and that you won’t get sick. Anxiety about a child or loved one wants confirmation that nothing bad will happen.

There are plenty of situations where we can gather reasonable information and make thoughtful decisions. There are also limits to how certain any of us can be.

For someone struggling with anxiety, trying to close that gap completely can become exhausting. One answer leads to another question. Reassurance works for an hour and then doubt returns. You check once, feel better, and then notice something else.

Part of exposure-based treatment is learning to recognize when you have enough information to move forward, even though anxiety would prefer more.

That might mean allowing a question to stay unanswered. It might mean making a decision without checking one more time. Sometimes it means noticing, I really want reassurance right now, and giving yourself an opportunity to see what happens if you don’t immediately seek it.

This work takes practice. We are changing patterns that may have been reinforced hundreds or even thousands of times.

Exposure Therapy Should Be Collaborative

People sometimes come into therapy nervous about exposure because they picture being forced to confront their worst fear immediately. That is not how we approach exposure work at North Shore Professional Therapy.

We talk about what we’re doing and why we’re doing it. Exposures are chosen intentionally and connected to what you want to be able to do differently in your life. You should understand the skill you are practicing and have a voice in the process.

There will likely be discomfort. If there weren’t, we probably wouldn’t be working with the fear very directly. But discomfort is different from being pushed into something without understanding it or agreeing to it.

Often, the things people want back from anxiety are pretty ordinary. They want to drive to work without planning their route around panic. They want to enjoy dinner without monitoring their body. They want to eat at a restaurant without spending the meal worrying about whether the food will make them sick or be able to take care of their child when they have the stomach bug. They want to go on vacation, speak during a meeting, exercise, spend time with friends, or let their teenager go somewhere without checking their location every few minutes.

That gives us a reason for doing the harder parts of exposure work. In therapy, we work together to really find your “why” so we can use that to generate courage and change. 

When Anxiety Has Started Limiting Your Life

Anxiety can become very good at making its rules feel reasonable.

Take this road. Check one more time. Ask someone what they think. Make sure there’s an exit. Look up the symptom. Rehearse the conversation again.

One rule usually doesn’t change your life very much. The problem develops as more rules get added and more decisions begin revolving around preventing anxiety.

ERP and other exposure-based treatments give us a way to examine those rules and gradually test what happens when you respond differently. Over time, many people find that they can do more without needing to feel completely certain, prepared, or calm first.

At North Shore Professional Therapy, we work with adults and teens experiencing anxiety, including health anxiety, panic attacks, social anxiety, driving anxiety, emetophobia and other specific fears, avoidance, and anxiety related to difficult or traumatic experiences. Treatment is individualized and may incorporate exposure-based strategies and ERP alongside CBT, ACT, EMDR, somatic approaches, and other evidence-based interventions based on what you are experiencing.

If anxiety has started affecting where you go, what you do, what you eat, or how much time you spend checking, preparing, avoiding, or looking for reassurance, we can work together to understand the pattern and begin changing it.

North Shore Professional Therapy provides anxiety therapy in Topsfield, Massachusetts, as well as virtual therapy for clients throughout Massachusetts. We have seen many clients effectively tackle their anxiety and get back to living the lives they deserve and want.
