I am in a dilema, out of six sister's only three of us have been looking after mum for the last nearly 3 years mum was diagnosed with AD about 4 months ago she is slowly getting worse she has been on Aricept nearly two months.The problem is this one of my sister's has just come home from travelling around the world for the past 5 month's and is saying I need to take a step back from caring for mum and let the professional's take over, but they have told us they can do no more. I have a bad back which is not getting any better and also have to look after my daughter who has rhumatoid arthrtis and has lost all mobility. How do I step back if they are not prepared to step in, said sister is off to Lanzarote for at least 3 months your thought's on this is appreciated.
