Hi, My fathers wife I was told is Bipolor. My father has cancer and she has been left in charge of giving him meds at home and all other care. She calls us and tells us he needs rest so we cant visit or call but then has her family over. My father has whispered on the phone that her family is there and not good. This concerns me because the doctors are telling him he has chemo brain and will think things happen when the dont and his wife is left in charge to clear things up with him on what is really going on. She also always watches shows where people murder their spouse and try to get away with it. I dont want to jump to any conclusions however if she is bipolor are these signs of bad things? Should i speak to my fathers doctor and tell him/her that we were told she is bipolor and what is going on?
