My mom has mixed dementia diagnosed a year and a half ago. She lives alone and recently has started having carers 4 times a day. She has never been much of a mom tbh but I have taken on the responsibility of everything appointments, dealing with GP, carers, pharmacy, shopping, ordering her ready meals and dealing with bills. She constantly bad mouths me to anyone that will listen saying I don't visit her etc which is fine I get she never liked me and accept this is part of the disease. What I really can not deal with is the lies she tells the carers mainly that my youngest daughter is a tart who sleeps around and brings boys home completely untrue. Shes always favoured my eldest daughter and treated my youngest terribly even before the diagnosis but to say such things to a complete stranger is unforgiveable. She recently started bad mouthing my husband saying I can’t understand why you married him he's thick and stupid just like your daughter. She constantly tells carers what a terrible mother I am which is rich coming from her. I’m literally at the point of walking away I have done so much taken unpaid leave from work to look after her but nothing is ever enough. My brother who does nothing for her is the golden boy, I’m thinking that walking away would make her realise but I know my brother won’t step up so I'm stuck.
