My father-in-law is in the final stages of copd/emphysema. When the doctors have tried to talk about end of life decisions, he acts as if he doesn't hear them. He has refused any type of pallative care or hospice. He does not want any type of pain management or anxiety medication either. He is in complete denial about his condition. How do I help him face the future? I hate the thought of him gasping for breath and suffering in his final days.
