So I've been suffering from depression and anxiety for a while now.  Therapy didn't really help, I've tried counselling once or twice but it didn't help.  So I thought I'd try medication.  Enter sertraline; I took one 50mg pill, had an anxiety attack and ended up running home to stay with my parents.  Didn't think it was because of the sertraline, took 2 more, then tried to masturbate and had an 8-hour-long panic attack; shivering, nausea, muscle spasms that made me feel like I was having a heart attack, you name it.  Since then every bodily sensation even slightly out of the norm (eg. sexual arousal, getting slightly drunk, having a shower) gives me a panic attack and makes me feel like I'm gonna die.  Then I feel for hours afterwards like someone has wrung out my stomach like a wet sock.  I had this kind of thing before, but never really this strong, and never to do with sexual arousal.  It's been 3 weeks now and to be honest it isn't getting much better.  Is this normal?  Do I have some kind of PTSD based around sex now?  Is it gonna get better?
