i have been under panic attacks too even when i feel i am quite calm and relax. why is this so? my muscles tend to get stiff and i have this sensation that my jaw is locking up plus i have this headache on the right side of my head. i'm kinda scared too because sometimes this happens when im driving alone and i feel like i lack my senses and concentration. but still i can manage to drive with my cold feet and hands too. whats odd is that sometimes i feel totally normal and poised. but at times i'm just to freaked out. you think i lack vitamins or something? something to ease my mind besides the meds i take for panic attacks?
