My 94-year old grandmother has always been an unpleasant woman. However, she is now downright mean and vile to everyone who comes in contact with her. She refuses to eat, claiming that the food is not prepared correctly. She will not even say "hello" to me or my family when we visit; instead, she immediately complains about something "horrible". I can no longer get her to even smile or say a single kind word. Her current assisted living facility is threatening to evict her if her mean attitude doesn't change. Please help me find a way to address this! My prayer is that she is able to find happiness in whatever years she has left.
