I feel like I'm going crazy lately. For the past few weeks I have felt awful.  I've had chest pain radiating down my arm, heart palpitations that don't seem to quit, lately I've been so nauseous it's been hard to eat. I've been to the ER 3 separate times and left every time with no answer and all of my tests come back great. My GP thinks it's anxiety and prescribed me sertraline, but I've only been taking it for a week and a half. 

It seems like this all came out of nowhere. I've had anxiety before but never experienced the physical side of it. And feeling this way only causes me to have more anxiety so it's a vicious cycle.  

It seems like I just cannot get myself to calm down and my heart feels like it's racing. It's hard for me to believe this can all come from your mind. Anyone else experience similar things? How do you deal with it, if so?

It's only been going on a few weeks but I'm starting to feel like I'm never going to feel like myself again. I've had a few days in between where I've felt alright but then it's right back to the scary stuff again.
