There's a phrase people get told in the middle of difficult moments that almost never lands the way it's intended. Just calm down. Anyone who has actually experienced anxiety, panic, shutdown, or chronic stress knows the gap between hearing those words and being able to do anything with them. The body is doing something the mind cannot override. Understanding what's actually happening underneath is one of the more useful things anyone can know.

There's a particular kind of exhaustion that comes from never quite being able to land. The body is technically at rest, but the system underneath is still working. Sitting on the couch, but listening for the front door. Falling asleep, but catching on a noise from outside and waking up scanning. Nothing dramatic is happening. The body just won't stop watching.
