Sensitive or Anxious? The Distinction Is Harder Than It Sounds
Let me take something highly nuanced and attempt to break it down.
Sensitivity, as researchers Aron and Homberg define it, is a temperament trait characterized by greater depth of information processing, increased emotional reactivity and empathy, greater awareness of environmental subtleties, and ease of overstimulation. It exists across multiple domains — emotional, physical, sensory, relational — which is part of what makes it so easy to misread. My mentor once said to me, "A lot of things look like a lot of things," and nowhere is that truer than here. Rejection sensitivity alone shows up as a criterion or associated feature in diagnoses as different as borderline personality disorder, atypical depression, ADHD, avoidant personality disorder, and autism spectrum disorder. If someone is sensitive, they may present as autistic, as ADHD, as someone carrying complex trauma, as anxious, or as some combination of all of the above. The overlap is not incidental.
People arrive at the term "highly sensitive" in different ways. Some stumble across Elaine Aron's research and feel, for the first time, that someone has described their inner experience accurately. Others hear the phrase from a friend or a therapist and wonder if it applies. And some come to my office asking a version of the question that sits underneath all of it: is there something wrong with me, or is this just how I am?
The distinction between sensitivity and anxiety matters, though not in the way people usually hope. They want a clean answer. Sensitivity would mean this is simply your nature, something to accept and work with. Anxiety would mean something is broken, something to fix. The reality is more layered than either option allows.
High sensitivity, as Aron defines it, is a trait of sensory processing sensitivity. Roughly fifteen to twenty percent of the population processes sensory and emotional information more deeply than others. This is not a disorder. It is a difference in nervous system organization, one that carries both gifts and costs. (Has anyone made a comic for kids yet about the superhero Super-Sensitive Sally? They should.) Put plainly, it is the capacity to take in the world more fully than others… and to be undone by it more easily too. You notice subtlety. You feel things fully. You may also become overwhelmed more easily, need more time to recover from stimulation, and find yourself exhausted by environments others seem to navigate without effort.
Anxiety, by contrast, is a state. It is your nervous system responding to perceived threat, whether the danger is present or imagined or remembered. Anxiety narrows attention, accelerates thought, and mobilizes the body for protection. It is not a personality trait. It is a signal. But the signal can become chronic if your system never learned, or was never taught, how to return to rest. When that vigilance becomes the baseline rather than the exception, clinicians sometimes reach for the language of generalized anxiety.
The distinction matters, but so does the connection. Sensitive people are more prone to developing anxiety, because a nervous system that takes in more information is a nervous system more easily overwhelmed. If you grew up in an environment that did not make room for your sensitivity- if you were told your feelings were too much, if the people around you responded to your needs with irritation or dismissal- your nervous system may have learned that the world was not safe for someone like you. Sensitivity became paired with vigilance. The trait became tangled with the state. What was constitutional got buried under what was relational.
This is what I see in clinical work: people who have spent years believing their anxiety is simply who they are, when in fact it is a learned response layered on top of a temperament that was never the problem. The sensitivity was not the issue. The issue was that no one taught them how to live with it, how to protect it, how to find environments and relationships that could hold it without punishing it. It is, admittedly, difficult to be sensitive in this world. But experiencing difficulties is not the same as having pathology.
The work, then, is not always to decide which label fits. It is to get curious about what your nervous system actually needs, and to grieve the fact that you may not have received it early on. Sensitive people often do well in therapy precisely because they are attuned, reflective, and capable of the kind of sustained self-examination that the process requires. The same qualities that made life harder can become assets in the work of repair.
If you have always felt like your feelings are too much, the question worth asking is not whether you are sensitive or anxious. The question is what happened to your sensitivity along the way, and what it might feel like to finally have it welcomed.
