Hi all, I have had anx and pa's for about 11 years for the last 2 they have been non existent really. For the last 2 weeks they have come back with a vengeance :( . Well I had one today which made me extremely hot and felt like I couldn't breathe, I was out at the time and left the restaurant and came home. I'm really tired and laying in bed but don't want to fall asleep ad I'm scared it's a heart attack coming on and I might not wake up. Please someone help.
