I'm sorry that I don't have experience with the ailments, but I do have experience with the passing of my mother, who died as I held her. You seem to be a strong woman and I just want to tell you to hang in there no matter what happens..you and your husband are in my thoughts and prayers.
Oh by the way we are trying to get him calm enough to bring him home. We now have wonderful Dr. Psyc and medical that work well together. DON'T BE AFRAID TO FIRE your Dr if you don't like them. We did and have gotten great care sense!
