My 80 year old father moved in with my husband and I 3 years ago. His only health concern is arthritis and pain caused by the arthritis. He depends on me to basically do everything for him while he is content to sit back and act as if he is dying. I have heart failure, copd, a failing liver and pancreas. I live with the fact that every day may be my last. He always makes a big show of asking how I am but then ignores what I have said and goes into a diatribe of how bad he is and how he won't last much longer. How can I handle this?
