Rosemary, do you have any family member or a close friend to be your advocate? Seems to me you are fighting this battle alone. I can remember when my mom was hospitalized several times during the last several years of her life due to heart failure, diabetes and kidney failure. I had to always be at the hospital with some arguement or other as it seemed they were constantly sluffing her off. My dad and I finally were able to get her transferred to a hospital which had doctors who actually LISTENED to us and they placed her on peritoneal dialysis. This did prolong her life a few years and she didn't seem to suffer as much and lived to see our oldest daughter get married. She actually outlived dad!
It just worries me that you don't seem to have anyone in your corner .
