medical expenses due to amputation

I had a diabetic infection in my right foot in April which caused me to be a amputee. I have been through 5 surgeries since then and I have been diagnosed with severe arthritis in my left leg as well as losing my right foot.I have no insurance and having to appeal disability because they say I am not disabled or blind by their rules.I have to get a special custom brace for my left foot to help with the pain so I can be mobile again.any help would be greater appreciated.I have lost about 6 inches above my ankle and due to all my medical expenses I have lost everything. Thanks once again
