I don't know if this is a side effect or what. I'm on Wellbutrin SR 100 mg a day. I've been on it about a month and a half and it's helping my depression a lot. In fact, I rarely feel sad at all. One thing, though, is I've become apathetic to everyone. I'm excited about situations and things, but I don't really.. care about anyone. I'm not sad about leaving people I normally would be, I'm not particularly happy to be seeing people I should be happy to see.. I just don't care. I had this long time relationship with someone off and on, and it's been many years and I always cared probably TOO much, but like overnight I went to not caring at all. It's weird. I can't really get myself to feel sympathy for my friend whose cat is dying right now. I don't think this is particularly a good thing.. but then if I don't have anyone to hurt me, that would stop a lot of depression too lol but I don't know.. has anyone ever experienced this as a drug side effect?
