When I have a panic attack it very literally paralyzes me. I can not move or I will die, I can not call for help or I will die, I can not breathe or I will die. The weird thing is that I also feel that if I do nothing I will also die so it's a no win situation. All I can do is keep repeating "I will not die" sort of like a mantra. It keeps me going until the episode ends. Go see a shrink. The meds work.
