It is possible to get a special issuance for certain things, but with what you have listed there is no way you would ever obtain medical certification. I almost certain a Class 2 or 3 would not be possible either.

For clarity let me say that if you have any one of those conditions individually then you could get a special issuance very easily based on how the disease or disorder manifests itself, but when you have all of them combined it becomes exponentially more difficult.
