I full on admit when I am PMSing. I know if I cry at a happy movie. Or get angry because everyone around me is bugging the shit out of me. I know it. I accept it. When I had my first anxiety attack it was because of PMS. So when It hits (and all woman know when it is coming) I take my PMS relief pills from the drug store and in about 30 minutes I am returned to almost normal. Try and get your girlfriend, or wife to take them.
They will make your lives so much better.
