I think you have PMDD. About Every 4 weeks you are posting here, desperate. This affected me too. It doesnt really help knowing whats going on, because things feel genuinely rotten. I think the rest of the time, or immediately after the period starts, i had so many "good" hormones, that i MISTAKENLY thought everything was okay in my life, so really the time known as PMS is when we are facing reality, and the rest of the time we are fooling ourselves. Anyway, a gynecologist can help you with medication, if your parents will let you, to even things out. Good luck. I know its really really hard to deal with. A friend (so called) actually gave me a huge pin for my birthday one year that said "Moody *****"
