Severe PMS?

I am what a friend of mine calls a "time monster". For the first two weeks of my cycle, I'm totally fine. I don't get mood swings, my moods aren't extreme, and I'm collectively content. During the week before and the week of my interval, I become unable to control my emotion. I'll be skipping happy, afterwards hysterically sad, next unbelievably angry. I also feel the physiological effects of my emotion; i.e. I physically feel buoyant and bedside light when I'm happy, I have a feeling physically crushed when I'm sad, and I can almost be aware of my blood vessels constrict when I'm angry. Plus, my mood change at the drop of a hat. This issue is affecting my relationship and my chore. I am making an appointment with my OB-GYN, but I want to know if in that is anything I can do to counteract my symptoms until then. I'm contained by my "monster" phase right now. Help!!

You know you can become irrational when you get angry and lash out.

When you do feel angry, and this can ensue from one second to the next, help yourself to time out away from others.
