UTI that will not stop, please help!?

I've had frequent uti's since I was a little girl, but they have always been treatable in the past. I was taking pain medication at the beginning of this year after an accident and have since had the longest uti of of my life (about 10 months now). In the past it always went away with a lot of cranberry juice and some AZO max, not this time. I have been taking vitamin c (asorbic acid) pills at night before i go to bed bc it's always worse in the morning. This has not helped. I don't have insurance and have been to the ER twice and recieved antibiotics which also did not help. I can't afford to keep doing this as I'm still not working after the accident ($1,200 a visit). I drink about 10-16oz of 100% cranberry juice a day, i have cut everything else but water out, and i drink it constantly, all day. Cut my sodium as much as humanly possible, no sweets at all. I stopped taking baths, just showers. I've had kidney infections from UTIs before, this one hasn't progressed that far thankfully. The length of this is literally driving me crazy, I've even thought of suicide. I cannot sleep through the night without running to the restroom and after i go i cannot go back to sleep due to pain and discomfort. My husband and I have abstained from eachother for almost a year, this whole thing is ruining my life. Please, PLEASE if anyone has been through this and can give some new suggestions it would be appreciated. I have tried everything I can think of.
