Cressida I know you are independent but my example of a care home may ring bells.
My uncle lived 150 miles away from me. When he had to go to a care home his Social Worker advised me if at all possible to find one in the town he had lived and worked in for over 35 years because he said his friends would still be able to visit him, my uncle suffered from depression, not dementia. I took his advice and during his six years in the care home, he had a number of regular visitors, who shared his passion for Arsenal, or had worked with him or lived in the same road and shared the gossip.
I could only visit monthly and I would usually have lunch at the care home. One day I was chatting to another lady on our table and casually asked her how she enjoyed being there. 'I hate it here', she said. It wasn't the home she hated but she had given up a home and friends 200 miles away to live near her son and family on his encouragement. She moved, looking forward to seeing more of her son and grandchildren. Now she was there, they hardly ever visited. She was miserable, missing friends, home and familiar places
