When I feel that way, it has very little to do with hormones (I've always been like that), but I have three general coping strategies, in no particular order:
1) Talk it out with my husband and/or close friends and family
2) Write about it in my paper journal (occasionally online)
3) Crawl into bed and take a long, hard nap (or eat something, if it's related to my blood-sugar, which happens now and then)
Good luck, hon. Are you on birth control of any kind? That can either help or hurt, in situations like yours. Also, any kind of anti-depressant medication? Exercising regularly? Eating well? All that stuff factors into your moods... take a look at it and see where you might be able to improve an area.
