Day 11 on Prozac, felt like I was making progress, working out, eating better, taking time relax. Ironically as I'm listening to one of my relaxation tapes I descend into a full blown panic attack. I begin trembling, the anxious thoughts begin to fill my head, and I worry that I'm having a catastrophic response to the medication. I'm so frustrated right now, it just came on so randomly. How do others deal with the rush of negative thoughts that come through your mind in situations like this?
