I have an anxiety disorder and I've been noticing that lately especially that when hit by triggers I go into a brief catatonic state, then I feel very delirious for a while after that. It's sort of like being paralyzed by fear. The worst one was last week and I don't think I even was able to think for a few minutes. I really don't know how long I was frozen, but it couldn't been more than a couple of minutes or so. Last night, it happened again, but I could think, but the thoughts were so overwhelming that I couldn't do anything else but sit and stare and think.
