Depressed and I need advice.?

I started a depression medication about a month ago. The doctor put me on Wellbutrin, I was feeling a lot better until I went back to the doctor and she put me on progesterone. (That's a whole other story.) Anyway, I have just been feeling awful lately. I have been having more suicidal thoughts, but I just want to make it clear that I would never actually kill myself or attempt too. Does anyone think that it may just be the progesterone that is causing me to feel more depressed since it is a hormone? Or do you think it's just my Wellbutrin?
