My mum has always abused alcohol and other substances. However, she has become very frail. She has never looked after herself properly. My dad is struggling to cope with her and look after her. He is older and has his own serious health concerns. I cannot deal with her emotionally recently because she refuses help. I'm concerned as she gets less mobile and needs more care, how will we deal with that. She refuses to have a carer (they can afford it without any concerns). Dad won't be able to do it. I can't do it because I honestly cannot cope with her at all. She's very manipulative. What happens in these scenarios? I'm very concerned about the future and i feel like I can't prepare or plan for it.
