My brother and I are at breaking point an desperately need advice. My mum has recently been diagnosed as having mixed dementia and is severely sight impaired but has no insight into her conditions and says she can do everything the same as always , my father has been diagnosed as having critical cardiac failure and kidney failure and has been put on palliative care with a hospice. This has all happened within the space of 10 weeks and it has been 10 weeks of hell. My brother and I have been proactive and have got social services to help them with care packages and some adaptations but mum and dad keep telling everyone they don't need any help and their son and daughter will do it and even turning people away. Dad is in hospital and mum doesn't like being on her own at night but doesn't realise that she get up 8-10 times a night then gets up at 5am and calls us liars if we say she did. Either we, my aunty or family friend (both retired and in late 70's) have to stay with her but none of us gets any sleep when its our turn. My brother and I have very busy jobs and cannot work without sleep and my brother is getting into trouble for taking so much time off to arrange stuff for them or because he is so tired. We are both mentally and physically at breaking point. Everything with my parents seems to be a no or a negative response, with their favourite answer being we'll see when we recommend something to them like a night sitter. They have money and could pay for extra care but are refusing - should we walk away to force their hand to accept more help and not keep thinking my brother and I will do everything 24/7 for them?
