depression
"Looking back, I think I've had anxiety and depression most of my life. When I started to have mood swings and also feel like crying almost every day, I finally decided to seek treatment. This was about 5 years ago. The generics for Welbutrin and Lexapro helped, but I still had many times when I was depressed and somewhat suicidal. My psychiatrist tried prescribing several add-on meds, but either they weren't effective or caused side effects like weight gain. I am now on 100 mg of lamotrigine, and I don't think I've ever felt better! I am cheerful, motivated and feel like myself, without anxiety or depression. Only side effect is that  I sometimes feel itchy on my scalp, arms or legs. No rash."
