Not Sure What To Do!!!

I've always had major mood swings. But recently they have been a major issue. And it's becoming an issue in my relationship. Thank goodness my SO has ALOT of patients. 
These last couple weeks I have just snapped for no apparent reason. I woke up yesterday completely fine. It was my last day of my period, it was gonna be a good day. Get to work, nothing goes wrong. But as soon as I clock out my mood just changes. 
Moral of the story, I get home and the computer pisses me off and I just freak out and start bawling. 
I'm noticing I'm starting to bawl for no apparent reason. 
My moods have been changing rapidly, and I feel crazy.
