Sertraline
"I've been on Sertraline for 5 months now I started out at 50mg and it seemed to be ok my anxiety attacks were becoming far less and I was a lot happier then about 3 months later I found I was having panic attacks again and now for the last month I've been on 100mg my mood is so bad it's affecting my relationship and I always just feel down and worthless I'm going back to the doctor soon to hopefully sort it out"
