Postpartum and on Depo Provera birth control

I gave birth in September and received my first shot of depo provera for birth control. I've since gotten 2 more shots.

I have a history of depression and anxiety, but I haven't been on medicine for it in around 2 years. I was not diagnosed with postpartum depression.

Ever since I gave birth, I've been having terrible mood swings, I'm depressed a lot, mad about stupid, little things just as frequently, but every now and then I feel super motivated and mildly happy.

I had a friend tell me that she had to be put on antipsychotics after being on depo provera for a few years. I don't want that to be the case for me.

I haven't had a chance to go to the doctor, so I wanted to post on here and see if anyone had any suggestions. I wanted to talk to my gynecologist about other birth control options at my last appointment, but I wasn't at my usual office.
