You might talk to your hospice coordinator about this. I was a hospice vollenteer and our training helped us to come to accept death as a natural part of life.
We just lost my daughter in laws father at 62 from lung cancer. He put up a valiant fight but it took over his body and in the end he was so sick, his body could not go on.
It is a great mystery about death in general concerning God and the after life. I think I might be uncomfortable with the gallows humor involved in care giving and losing people daily.
I am hardly a professional though.
