My SIL has told my mum we are on holiday for 2 weeks despite me asking her not to. She has also said I will not call her. I can't understand why as she knows mum will get confused and upset. My mum is now convinced no-one will be coming to see her, she will have no food and will be left to starve. She is pushing her panic button almost daily. I've tried to reassure her and put messages on her white board but nothing helps. I have told her I will still call her late pm. I have been planning this Panama Canal cruise for over a year for my OH's 60th. I have done all I can to make sure she is looked after while I'm away.
