I have an elderly friend who I go out and about with. She's 83 and lives by herself. I've known her for over 50 years and I regard her as my 'second mum'. She moved to live near me 7 years ago and she has no relatives close by. Over the last four years her memory has been getting worse and her hearing and sight are not good but she flatly refuses to have any checks. She forgets information given to her even after a short while. I am most concerned as she has recently 'misplaced' money and had her wallet stolen and she will not report it to the police. She gets extremely agitated at minor events and has often threatened to sue shops if they do not address her demands immediately. She has previously thrown me out of her house for suggesting eye/hearing tests and she is very vicious vocally. Last year we went on holiday for 3 nights with another friend and it was a catalogue of disasters. She was trying to scribble notes in the dark, 'lost' a ring and her handbag and she had a fall because she hadn't heard a warning shout that the wall was there. She also verbally assaulted me in front of a pub full of people. I really don't know where I go from here and would appreciate some advice. I am 60 next year and am registered disabled with mobility problems and clinical depression. I love my friend dearly but am finding this tough going. Any advice please?
