Periods make me depressed

Mandy

I’m taking birth control but ever since I can remember I go crazy on my period. I’m an emotional wreck. It’s now effecting my relationship. I know that being emotional is normal when having a period but what I go through is full manic, depression episodes. I was diagnosed with depression a few years ago and I take Prozac for that now. It works wonders, but only when Im not on my period. It’s like it doesn’t work at all once I get my period. I’m not sure if I’m going crazy or this is normal. I don’t know what to do.
