I am a crazy person a week before my period. I will cry for no reason, start fights with my b/f?

I know it's PMS, but it's like a whole other level. I will think my b/f means something hateful when I know it's just a normal statement, I will cry at TV commercials and I feel very anxious like I just want to scream, it's sometimes even difficult to function at work. It only happens about a week before my period. Is it just PMS or am I going crazy?
Does anyone know anything about PMDD?

It could be PMDD. I have it too. I would suggest you speak to your doctor/obgyn and tell them about it. THere are medications for this. There is also counseling. Learning to understand your mood swings as just that, mood swings, and learn coping techniques. You know he didn't mean that last comment in a bad way, take a deep breath and rationalize that to yourself and try not to kill him. Avoid those kodak moments on TV. Try deep breathing and relaxation techniques. You may want to increase your exercize that week, it helps. If you feel really out of control, despite being able to recognize your feelings as over the top, go to your doctor. They will help you. Check out Webmd for more information on PMDD.
