PMS or crazy?

Either Aunt Flo is on her way, or I am losing my fucking mind. There was nothing on tv when I got home today, so I just left it on HBO which was playing "Fools Rush In." That's the crappy movie with Matthew Perry and Salma Hayek. I don't even like this movie yet I found myself crying hysterically through most of the last 30 minutes. What the hell is wrong with me?
