Depro Provera

I have a question. I am on depro provera right now, I just got my 4th shot three days ago so I`ve been on it for 9 months now. My boyfriend just broke up with me because of my mood swings and the fact that I always wanted to be around him. I thought it was because of the shot because none of that happened before but he said I can`t keep blaming it on the shot. What do you guys think? I`ve had mild depression, Dr. Jackle and Mr. Hyde mood swings that change every other week, and I have a weird appitite. Is that because of the shot?
