I dnt really know what causes my anxiety attacks icould be havin a normal day an all of a sudden feel like i can't breathe, if i dnt sit or lay down i begin 2 sweat like crazy even if its cold an then i'll black/pass out. I was a little embarrassed early bcuz i hate when this happens in public. about an hr ago in bi lo i felt an attack cumin, i was in the middle of grocery shopping with my 3yr old an 2yr old, i had 2 go sit at the booth in the deli b4 i hit the floor in front of every1, Some ladies from the bakery noticed i was about 2 pass out an couldnt control my breathing, they came 2 c if i was ok an if i wanted a drink. I just wana know Why does this keep happening its scary cuz i can't control it. i thought i was normal but it gets worse everyday.
