Congrats. in beating the cancer. So sorry you are dealing with the fog and neuropathy. I am a chronic painie with a hefty side order of neuropathy due to failed back surgery. The fog is from Fibormyalgia that was dxed back in 1976. Neuropathy can be disabling. If that was all I had, I would still be disabled because mine is severe. You have been given good advice. Any info. I would give you would be outdated as I was approved in 95. I can safely say, don't give up regardless of how long it takes. You will most likely need that safety net as time goes by, if not already. There are knowledgable and caring folks here to support and wisely advise you. Hang in there.
