This is good information, thank you. Gosh, I do hope your mum isn't developing dementia as well. I would still say respite care could be a good idea to help you all figure it out. I don't even dare to speculate how you might go about getting mum checked out - would she go just for a check up, well woman or otherwise? It's hard to tell if it's her generally or her caring that is making her behave like this unless you can go by process of elimination.Dad is probably 5 years in his dementia journey - his mobility is ok and walks with stick , he maintains control of his personal care. Mum in control of cooking and dispensing medication - 5 days a week she has external cover - dad at care centre 2 full days and 3 afternoons covered by carer coming to house. Financial situation shared by sister and I and we have viewed care facilities for full time care for future - she is unwilling at this stage to proceed down this route - he is on waiting list for 2 homes. We are assisting to the best of our ability but it’s not always recognised or received well. Am struggling when I hear that we don’t live with it 24/7 but the resentment and negativity certainly do ripple out to those trying hard to be supportive.
