I have been suffering from health anxiety mostly and was on prozac for a week but gave me really bad side effects have also tried Zoloft and paxil for a few days but they were worse with side effects. Recently I started getting chest pains in my heart area and started feeling nauseated and like I will pass out and pain under arms etc , I went to the ER four times all times the ECG and blood tests were normal and also had a echo and Holter montior 4 mths ago all normal. I also had 3 CT scans within the last year and an MRI 15 months ago all was normal . 
This feeling of chest pain is scary and this feeling of dizziness and that I will pass out , and also when trying to focus feel like I can't and will pass out or feel seizure like. Does anyone experience this , I get it on a daily basis for maybe 8 mths now
