thanks for the responses. i am only 34, so i'm pretty sure i can rule out menopause, hopefully! i am slightly scared about stuff like prozac, but if you think i should give the st. john's wort or the primrose oil a try, i will. what's so weird about it is that i know it's all physical, yet i become SO convinced that everything is just awful for a couple of days. i almost wish i would become really cranky, like other people do with pms, but i don't- i get so SAD. then, the next day, i'm running around smiling like an idiot. go figure. anyway, thanks.
