maybe a different med would affect you differently. it is worth a try...

my anxiety makes me feel like I am having a heart attack too. I am terrified of drs though. I console myself with the thought that if it truly was a heart problem, I would be dead by now as often as it happens so it really only is anxiety. I don't need to look stupid in front of a doctor to tell me that. so when the chest pains come on and I am certain I am going to die and feel like I need to go to the emergency room I just remember all the other times it happened and I didn't die then so I know it isn't my heart and it will go away eventually.
