I was. In fact, I was hell on wheels for at least a week before my period started. I was mean and nasty and angry. I didn't know then that I had bipolar, so my family and I just assumed it was a really ugly version of PMS. Funny how I never knew that's what it was until long after I passed through the menopause at age 47.....but I'm glad I don't have to go through that anymore, even if I AM still bipolar. Lol.
