Rewiring Anxiety: Fear vs. Anxiety, Neuroplasticity, and the Reset

Part 2 of 3

Recap: Part 1 “How to Read Your Body and Stop Interpreting Everything as Anxiety” showed how mislabeling bodily activation shrinks life—and how accurate naming, reframing, and simple drills restore clarity. Part 2 tackles why some systems stamp everything “anxiety,” and what it takes to recalibrate them for good.

When Everything Feels Like Anxiety

So, why does nearly every internal sensation begin to feel like anxiety for some people? This often occurs because their nervous system has been fundamentally reshaped by significant past experiences it had to survive—whether through prolonged exposure to trauma or a single, intensely overwhelming event that left the system critically overloaded. Under such an immense and sustained load, the insular cortex, responsible for nuanced interpretation, effectively ceases to sort internal signals cleanly. The primitive limbic system, in its attempt to protect, floods the insula with an undifferentiated torrent of interoceptive signals, leading to a complete collapse of precise classification. As a result, any spike of sympathetic arousal—be it genuine excitement, everyday stress, frustration, anticipation, or even anger—gets indiscriminately stamped with the same broad, alarming label: “anxiety,” regardless of its true origin or meaning.

Comedian-author Sara Benincasa describes how panic slid into agoraphobia in college until “safe routes” became the only routes. It shows how mislabeling + avoidance (negative reinforcement) quietly shrink a life—and why retraining the interpreter and taking graded steps reverses the spiral. Days went by without leaving the apartment; errands turned into ordeals; avoidance bought ten minutes of relief and cost months of life. Friends finally intervened, and with therapy and gradual exposure she rebuilt capacity—first the hallway, then the block, then the subway. The feelings didn’t vanish; her labels and actions changed, and her world grew again.
