THE WORST PERIOD!!!

Hey y’all so I have got to be one of the most unluckiest females ever. My periods are terrible and it’s been like this since I was 11 years old. I’m 17 now and I’ve been on the pill and it did help m cycle symptoms A LOT but it messed w my emotions sooo much. I was depressed and always crying for no reason. So what are things I can do / take to help me w my cycle? On my cycle I feel nauseated most of the time, I get light headed (one time I passed out at work) , when I have to use the rest room I get a sharp pain from the back.. I can’t explain it.. I can’t eat , I’m hot 😒 and cramps are the LEAST of my worries even tho they’re pretty bad. Someone please help I do NOT wanna be on any form of birth control. (I want children in the future and I don’t wanna mess up my fertility)
