Doctor just doesn't care about my pain?

-sigh- I'm seriously just almost ready to lay down and die at this point, I'm so sick of fighting, it's not getting me anywhere, but I may as well ask. I just got home from a doctors appointment, and he really didn't seem to give a crap about most of my symptoms... which is typical. (Getting a new doctor won't change it, I've been through maybe 30 in the past four years, they are all this bad or worse it seems.) But most of my other symptoms I can do some sort of patch job for on my own with the resources available to me OTC. My pain, I no longer can, AT ALL. NSAIDs taken orally make me violently ill, and as that's been that way for several years, Tylenol being the only other thing available, I've built up a tolerance to where it can't help at all in safe doses. Everything else I need a script for, but my doctor just asked if I'd "tried naproxen" and acted like it was the only thing that existed. O.o I don't know the names of the drugs, but I know I've read about them making extended release NSAIDs with stomach gaurds and such for the treatment of arthritis and such things, but they are new and prescription only. And then there are stronger things which cannot be used long term, and I understand that, but it's something. Or I've read some people are prescribed NSAID self-injections and that sort of thing. But my doctor wouldn't listen, and I have nothing. My pain level is never truly tolerable, never below a 7, and some days I can't even walk. I'm only eighteen and on my BEST days, I walk with a cane and a hell of a limp, and every movement makes me want to scream. I've ended up taking several trips to the ER lately when I've gotten migraines and things like that, because along with my normal everyday pain, it becomes just completely intolerable, to the point where suicide seems like the only logical option, where I'm never suicidal or truly depressed otherwise, it just gets to be too much and I can no longer handle it on my own. But I can't keep going back to the ER for things like that, obviously, and they tell me to follow up with my primary care physician, but he won't even listen. Does anyone know where you go at this point? I've done ALL the alternative stuff already, and I've kept up with it, but it's not helping... physical therapy, chiropractic care, acupuncture. I exercise as much as I possibly can in my condition, and I eat right. I don't know why I'm in pain, and I really just have no idea what to do. But I had to give up EVERYTHING... friends, school, my hobbies, any chance of ever being able to live my life, because I'm in pain that it's completely and entirely untreated, and this isn't living. I'm just not sure where to go from here...I can't force a doctor to listen, or to help me, or anything like that. But I can't keep doing this either. There is no point in it. Any advice? Or is it just hopeless?
