Take care of yourself tedo, it sounds like it could be hard for you after the accident then going in for knee replacements! I'm sorry you won't have anyone to help you with that.

Your aunt may or may not "come back" but letting her do her healing in her own way and time instead of pushing so much might help your relationship with her. It sounds a little like your roles are reversed right now and she's like a child that says "I hate you!" to her mother but the mother knows it's not true. I bet she'll come around when she is through this grief stage from her life changing so much.
