hi. i think i have a problem. recently, i have been experiencing severe mood changes. i go from really happy and then my boyfriend will say one thing that shouldn't make me mad, but i get so angry. i argue intensely. i am smoking, which i told myself i would never ever do. i cry at dumb things. i don't get it. could it have anything to do with the fact that i have been on the pill for the last 3 months?
