My wife has Alzhiemers I'm disabled

My wife was an RN for 35 years.  About 5 years ago she started having difficulty performing her job. She stopped working as I was finally doing well at work even though I had 2 back surgeries I was excelling. Then she started struggling with memory loss and we took her to a Nuerologist who diagnosed her with early onset alzhiemers. My only goal in life was to support her and care for her and support her. Then more of my disks started failing. I have 2 that are currently herniated and 6 with stenosis of various degrees. I also suffer from severe arthritis in my back hips and knees and have peripheral nueropothy causing both pain and numbness in my feet. All I want is to be able to keep our house and take care of her. My back is a mess and she has continued to deteriorate. We relocated from NC back in july and it was supposed to take 45 days to sell our house there. after 5 months we finally sold it. 4 days before closing our buyer passed away. We have applied for ssdi and expect funds in a month or two but until then I have sold everything I owned to buy food and pay what bills I could. I fear I may loose this house and we could end up homeless. Please help me be able to make the rest of her life as comfortable as possible. We need funds bad for bills, food, meds, more bills, and medical bills.
