I asked a client recently what it would feel like if his anxiety wasn’t there.
He could not remember a time in his life when he did not feel anxious. Not a period of his childhood, not a stretch of months in adulthood, not even a single afternoon where the hum of vigilance was completely absent. He described it the way someone might describe the color of their eyes or the fact that they were left-handed.
He looked at me like I had asked him to imagine breathing underwater.
“I genuinely have no idea,” he said. “I think I would feel like I was forgetting something important.”
What he was describing was a signal working exactly the way it had been trained to work. His anxiety was doing its job.
Anxiety, in the way most people experience it, is not evidence of a broken nervous system. It is evidence of a nervous system doing its job under conditions that taught it to stay alert. The problem is not the anxiety itself. The problem is that the conditions that required constant vigilance are no longer present, but the nervous system has not been told that the job has changed.
I wanted to talk to him about what his anxiety was actually protecting, because until he understood that, the anxiety would keep doing what it believed it needed to do, which was to keep him safe from something that felt dangerous a long time ago.
Elizabeth Stanley, a researcher who spent years studying how stress affects the nervous system, describes something she calls the window of tolerance. This is the range within which a person can function well, think clearly, and respond to life without feeling overwhelmed or shutting down. When someone grows up in an environment where they feel safe and their needs are consistently met, that window tends to be wide. They can handle a lot of variation in their experience without their nervous system going into alarm.
But when someone grows up in an environment where things are unpredictable, where safety is not a given, where the people they depend on are volatile or inconsistent or emotionally unavailable, that window narrows. It narrows because the nervous system learns that the world outside a very specific range of experience is dangerous, and anything that pushes beyond that range needs to be met with vigilance, with bracing, with the kind of monitoring that we call anxiety.
My client had grown up in a house where both of his parents drank. It was their nightly ritual. Not binge drinking, not the kind of thing that resulted in police visits or hospital trips or scenes that the neighbors would talk about. Just wine with dinner that became wine after dinner, beers that accumulated through the evening, a gradual loosening that changed the house in ways that were hard to name but impossible to ignore. Some nights the drinking made them warm, affectionate, relaxed in ways they were not during the day. Other nights it made them irritable, or withdrawn, or prone to arguments that would start over nothing and spiral into tension that filled the house.
He learned to read the signs early. How many drinks in they were. The quality of their laughter. The sharpness or softness in their voices when they spoke to each other, his siblings, or to him. He learned to stay small on the nights when small felt safer, to go to his room before things shifted, to navigate an environment where the rules changed depending on variables he could monitor but not control.
This is not the kind of childhood people think of when they hear the word trauma. His parents were not violent. They were not neglectful in obvious ways. They fed him, clothed him, sent him to school, told him they loved him. But they were unpredictable in ways that mattered to a child trying to make sense of the world, and unpredictability, when you are young and dependent, is its own kind of danger.
Stephen Porges, the researcher who developed polyvagal theory, describes this process as neuroception. It is the way the nervous system scans the environment for cues of safety or danger below the level of conscious awareness. The brainstem and limbic system are constantly evaluating whether a situation is safe or threatening, whether to engage or defend or withdraw. A child does not decide to monitor their parent’s mood. Their nervous system does it automatically, because that is what nervous systems do when safety is conditional.
And here is what matters most. The nervous system does not forget what it learned. It does not update its threat assessment just because the person grows up and moves out and builds a life where his parents’ drinking is no longer a factor. The neuroception that developed in childhood continues to operate in adulthood, scanning for the same cues, bracing for the same shifts, staying vigilant against dangers that no longer exist in the same form.
This is what my client was living with. A window of tolerance that had narrowed so much over the years that almost anything outside a very controlled range of experience felt threatening. A job review that was mostly positive but included one piece of constructive feedback would send him into spirals of anxiety that lasted for days. A friend canceling plans at the last minute would leave him bracing for rejection even when the reason was completely benign. His partner’s tone of voice during a normal conversation could trigger the same vigilance he had learned to employ as a child reading his parents’ moods.
He would tell himself that his anxiety made no sense. He would remind himself that he was safe, that nothing bad was actually happening, that the situations triggering his alarm were objectively minor. And none of it helped, because the part of his nervous system generating the anxiety was not listening to his logic. It was doing what it had been trained to do, which was to protect him from unpredictability by staying alert to every signal that things might shift.
What he did not understand, and what I wanted to help him see, was that his anxiety was not irrational. It was precisely rational given what his nervous system had learned. The anxiety was a signal that said: stay vigilant, because the environment is not safe, because things can change without warning, because letting your guard down means being caught off guard, and being caught off guard as a child felt unbearable.
The question was not how to get rid of the anxiety. The question was what the anxiety was protecting.
In my experience, beneath chronic anxiety there is almost always something the person learned early on that they could not afford to feel. For some people it is vulnerability, the fear that if they are not constantly monitoring and managing, they will be blindsided by something they cannot handle. For others it is helplessness, the terror of being in a situation where they have no control. For my client, what sat beneath the anxiety was a deep fear of being too much, of taking up space in ways that would make people pull away.
He had learned as a child that his needs were secondary to managing the emotional climate of the house. If his parents were drinking and things were tense, his job was to be small, to not add to the problem, to manage his own feelings so that he did not become one more thing they had to deal with. And the anxiety he felt as an adult was still doing that job. It was keeping him hyperaware of how he was being received, constantly adjusting to make sure he was not too much, scanning for signs that he had crossed a line or asked for too much or made someone uncomfortable.
The anxiety was not the problem. The anxiety was the guard at the gate, working overtime to make sure the thing beneath it, the fear of being too much, never had to be felt fully, because feeling it fully would mean confronting the reality that he had spent his childhood making himself smaller to fit into a house that could not hold him.
This is what I mean when I say anxiety is a signal. It is the nervous system’s way of saying: there is something here that feels dangerous, and I am going to keep you alert until we can be sure it is safe. The problem is that the nervous system is often working from information that is decades old, and the danger it is protecting against is no longer present in the way it once was.
When I asked my client what he thought would happen if the anxiety was not there, if he let his guard down completely, he said he thought he would be blindsided. He thought people would leave. He thought he would discover that he had been too much all along and no one had told him until it was too late.
And when I asked him where he learned that, he went quiet for a long time. Then he said, “I think I always knew it.”
But he did not always know it. He learned it. He learned it in a house where the people he depended on were warm one moment and withdrawn the next, where love felt conditional on his ability to read the room and adjust accordingly, where being small and undemanding was safer than being fully himself.
The work, then, is not about eliminating the anxiety. It is about recognizing what the anxiety is protecting, understanding where it learned to do that job, and slowly, carefully, teaching the nervous system that the conditions have changed. That the people in his life now are not his parents. That expressing a need will not result in withdrawal. That taking up space will not make people leave.
This does not happen quickly, and it does not happen through logic. The part of the nervous system that generates anxiety does not respond to rational argument. It responds to repeated experience. It updates based on what actually happens, not what you tell it should happen. And so the work involves creating experiences, small and manageable at first, where the thing the anxiety is protecting against does not come true. Where he expresses a need and the person does not pull away. Where he takes up space and people stay. Where the thing beneath the anxiety, the fear of being too much, is allowed to surface and be met with something other than rejection.
The anxiety begins to ease not because he has convinced himself it is irrational, but because his nervous system has gathered enough evidence that the old threat is no longer present. The window of tolerance begins to widen not because he has forced it open, but because the conditions that required it to narrow are no longer in place.
My client is still working on this. The anxiety has not disappeared. But he understands it differently now. He understands that it is not a disorder. It is a signal. And the signal is trying to protect him from something that mattered a long time ago, something his nervous system has not yet been told it can stop guarding against.
Peace my friends,
