Stress and Pain

So, my cysts are back. Yea. Not. I'm not supposed to be getting them. That's what the freaking birth contol is for. So, here is my philosophy on health care at the moment for anyone who cares.
I have had these stupid cysts for 6 years now. And they are so bad that they literally take command of my life for as long as they last. I limp, can't sleep, can't sit or stand for long periods of time... etc. Not fun. When i first got them in 9th grade i thought my appendix had just burst. I went to the doctor. How do you explain pain that is everywhere and extreme. Well, i explain the pain it was causing in my hip. so my doctor took some x-rays found nothing, told me it was just and inflammation in my hip and sent me home with pain killers and antibiotics. Well, 4 years later, i ended up in the emergency on morphine (and lortab that i had taken at home) and they finally did an ultrasound. i had been to the orthepedic doctor prior to this and he had scheduled an MRI which i was supposed to have the next day. well they found a cyst in the ultra sound that she guessed was about 3 cm. the MRI the next day found it to me 5 cm (the size of baseball) and when i went to the OBGYN she said that there wasn't really anything they could do but give me something for the pain and birth control and hope it helped. I was a junior in high school. So now, after 6 years, i finally decided to try birth control which is obviously not helping, and i have built up a tolerance for many pain killers. I've been to just about every kind of doctor imaginable for this, had every kind of test done, taken two kinds of birth control and who knows how many kinds of pain killers, and all the doctors do, is say, its just stress, take your birth control and here's a perscribtion for the pain. I'm sick of it. I'm 19. I want something to be done about this. When i have to change my life around because of pain, there is something wrong with that. or when i go home and cry because i can't let my life change, and i just worked for 6 hours (no sitting) after 3 hours of school and i can't feel my legs and i can't bend my toes because of the pain and the swelling, there's something wrong. And i want answers. Now.
