anxiety
"I have always been an anxious person. I'm a musician who performs a lot and have been taking Xanax for performing anxiety. About a month ago I went home to visit my family and started having really bad anxiety attacks that would happen every day. My heart would start racing, palpitations, hyperventilation and numbness in my arms. Every single time I thought that it was the end of my life and I was waiting for my heart to stop. I went and got blood tests and all was fine. Saw a cardiologist and my heart is ok.( I have bradycardia with rbm under 50). 

I saw a psychiatrist who prescribed seroxat(peroxetine) 10 mg before bed. It has been 2 weeks and I'm starting to feel better. Haven't had another panic attack. no side effects either."
