Tired of up and down hormones.

I have no clue what's been going on with my body lately. I don't know if it's my PMDD since I think I started my period, but it disappeared when I got on a new birth control, but I feel like choking myself. I'm serious. I am so tired of the extreme mood swings. It's like an endless roller coaster ride of being pissed, hurt, and upset. I never used to have it this bad that I remember. Little things just tend to set me off. Like right now I feel like crying just because my boyfriend won't talk to me anymore tonight. For some reason it hurts my feelings. He hardly talked to me today though tbh. I'm getting told I'm hard to deal with, but it's difficult to control the way I feel. This birth control is specifically designed to help treat my PMDD, but I just started it. And I know that my behavior isn't a side effect because I had this before I started my pills. I just don't understand.
