I am 19 years old and have been on Topomax for about 4.5 years, though recently I have just been really down and unable to do anything. It has bad yesterday and I started cutting myself. I don't understand what is happening to me, I am thinking it is the Topomax because I am usually a happy going person but recently I am only happy around other people. Has anyone else had similar troubles on Topomax??? I would really appreciate any feed back...THANKS!!!
