anybody else?

So when I get my period it's kind of like a thousand suns are arupting in my uterus. It also feels like rusty knives just stabbing me all the time. Endometriosis sucks ass. But anyway. No pain medication works for my cramps. Literally nothing. I'm considering trying horse tranquilizers so though. So I sit in bed all day and hold a heating pact to my stomach and have an ongoing whimper for about 48 hours. It's getting in the way of my school work because I can't be in class when the pain hits. And it strains me from my friends and family because I'm locked in my room for two days because I don't want anyone to see me like that. Does anybody have any advice on how to deal with this. Also should I go on the pill. I heard it helps.
