She had been in treatment for anxiety for three years.
She had tried two different medications. She had done CBT. She had a solid mindfulness practice. And she would have moments, sometimes weeks, where things felt manageable. Then something would shift, usually a period of more social demands, a work sprint, a family gathering, and she would be right back where she started.
When she came to coaching, she was frustrated. Not with treatment. With herself.
"I know all the tools," she said. "I know what I'm supposed to do. I just can't seem to maintain it."
About twenty minutes into our first conversation, I asked her to describe what the worst of it felt like. Not the story about it. The actual experience.
She thought for a moment.
"It feels like too much," she said. "Like there's too much coming at me. Sound. People's moods. The fluorescent lights in the office. The conversation I need to prepare for. My own thoughts about all of it. Too much information, all at once, and none of it going anywhere."
I asked: "Does it feel like fear?"
She paused.
"Not exactly. It feels more like overload. Like a circuit that's taken too much."
That description is not anxiety.
That is overstimulation. And they require different responses.
Two Different Processes
Anxiety and overstimulation can look nearly identical from the outside, and they can co-exist in the same person. Both can involve restlessness, irritability, difficulty concentrating, and a strong desire to escape whatever is happening.
But the underlying process is different.
Anxiety is primarily a response to perceived threat. The nervous system is running a risk calculation, and the result is alertness, hypervigilance, the need to solve or escape a potential danger. The cognitive component is typically prominent: there is a worry loop, a catastrophizing pattern, a specific fear structure.
Overstimulation in a highly sensitive person is something else. It is a processing overload. The highly sensitive nervous system takes in more information, processes it more deeply, and does so continuously. When the volume of stimulation exceeds the nervous system's processing capacity, the result is a kind of fullness, a feeling of being completely saturated, where one more thing, however small, produces a disproportionate response.
Why the Wrong Tool Makes It Worse
The tools for anxiety address the threat perception. Challenge the thought. Regulate the fear response. Build tolerance for uncertainty.
The tools for overstimulation address the load. Reduce input. Create space. Give the nervous system time to process what it already has before adding more.
Applying anxiety tools to overstimulation can actually make it worse. You are training yourself to push through the signal rather than respond to it.
What Changed When the Framework Changed
When she understood that she was not fundamentally anxious, but highly sensitive and chronically overstimulated, something significant shifted.
Not because the word was easier to hear. But because the framework was more accurate, and accuracy allows for a more useful response.
She stopped trying to make her nervous system not feel what it was feeling. She started working with what it actually needed: specifically, much more white space than she had been giving herself, especially after high-stimulation periods. Less back-to-back. Longer transitions. And a different conversation with herself when the overload arrived, one that started with "your system is full" rather than "what's wrong with you."
That is not a minor difference.
