I just want to sleep!

I just need somewhere to put my feelings. I just want to be able to sleep! Every night it takes me 2+ hours to fall asleep, and then I wake up every hour or 2 because it feels like I have to pee. I don't actually have to pee, but my body wakes me up because it feels like I have to. After that, I try to pee and only a few drops comes out and it burns. And it takes forever to fall back asleep because I'm in pain, and then I'll wake up again. I haven't gotten a good nights sleep in over a week. I haven't slept through a night in other two years. I have been to seceral walk-in clinics, I've been to a urologist, I've been prescribed several different medications, I've tried over the counter pain killers. Absolutely nothing works. I don't know what's wrong with me, but I just want to stop being miserable all the time. And I don't have a UTI. As I said, I've been to doctors many a time, and I've been prescribed medicine and nothing works.
