There is something called seritonin apathy that you can get from being on antidepressants. The Antidepressants help with the depression and keep you mood level but they also make it more difficult for you to experience positive feelings too. It's kind of like having no feellings a all. I've been there and am struggling with it now. Read up on seritonin apathy syndrome and it might explain some things to you. I only know this because I've been going through the same thing myself and have done some research and talked to my pdoc about it and he lowered my dose of antidepresant and it seems to be helping. Don't do anything without talking to your pdoc FIRST!
