Absolutely physical anxiety is a real thing. Maybe a better name is like, chemical anxiety, or non-psychological anxiety? Not sure if there’s a proper medical term for it. Every doctor I’ve told about it just said I must be lying lol

I have found some things that help though. You have to convince your body that you’re in a safe situation, whatever that means for you. For example: eating something nice, sitting in a quiet room, meditating, having a warm shower, etc

What I find interesting is that these are almost the opposite of treatment for psychological anxiety, where the goal is to interrupt rumination and prevent overthinking. Quiet moments alone with your thoughts is not ideal - at least that’s the impression I got when my ex showed me their therapy homework
