mabe it would be a good idea to go and talk to her social worker in depth about your worries, they may be able to direct you to the organisations that can help you.If you do feel she has the early signs of dementia then it would be worth haveing a mental health assesment done.As for her going into a home, i can understand thats the last thing you would want and mabe there is a way around that, but in saying that her self saftey is top of the list .And it does sound like she may well need 24 hour care.Which i do think will be an impossable thing to do considering your own problems.I would also advise you to contact the citizens advise buraue , you should be able to find some help and ideas there to .Best of luck hun and t,c for now x
