Health is failing. ?

So my health is failing. I have several terrible symptoms like nose bleeds and migraines that intersect with each other. Other symptoms include body aches, degenerative disk and the list goes on. It's a struggle to get out of bed each morning and I can feel it getting worse each day. I don't sleep and when I don't I don't recover. I've been to several doctors who have tried to diagnose me and we always go through the same routine, medication then treatment then surgery. It's at the point where the doctors and specialists no longer know what to say or diagnose and I no longer know what to do. I've had brain scans, xrays, mris, and the works but they can't find anything. I'm unsure where to turn next. I certainly didn't think it would be a yahoo board but I'm trying. The simple truth seems to be that my body is breaking down and there's no explanation. I'm in my 20s and I don't understand. I've made sure to eat healthy and exercise and stay away from bad habits. Definitely not looking for a cure here but any thoughts?
