I have been having panic/anxeity attacks for almost a year now. I have gone to the doctor numerous times thinking I was dying or having a stroke, only to be sent home with lorazepam. I want to know if I should be worried or not, I have had an EKG and a heart exam but it isn't enough to calm my mind!! I have papiltaions and pain, heartburn sweating racing heart, every symptom of a heart condition. I guess I just want to know if anyone has experienced this before or knows much about it, so I can ease my mind..
