i used to get them so bad i would lose consciousness, and that was on prescription pain meds. (there is nothing physically wrong with me either). i'd stay home from school all day screaming in agony begging my mom to call the doctor to give me morphine and muttering gibberish like prayers, although i'm not really religious. once i blacked out while driving. i was ok. After that, it was decided i needed birth control. it helps sooo much. no more pain! i highly recommend birth control, even if you don't need to control birth...er..prevent conception (silly word choice on the part of the manufacturers don't you think?).
but yeah, people don't seem to understand it. in high school i could feel them coming on and go to the nurse, say i needed to go home. she'd say, "well just wait a little bit and see if they go away." Yeah right! I'm going to pas out on your conrete floor lady, if you don't call my mom right now!
anyway, i feel your pain. get the pill. seriously!
