Canary is absolutely right, it is important your mum is near you so that you can visit. I too am an only child and had to make all the decisions, a year ago I moved my mother to a care home near me, a long distance from where she lived. Within two months it had become her new home, she loved it and she never mentions her old life. At the moment the whole concept of a care home is alien to you, and that takes getting used to. I used to have to steel myself for every visit in the first few months, but now it is as you say, the new normal. You're doing the right thing.
As for her friends, only one of them kept in touch. The others lost interest as soon as she left her flat, it was as if she no longer existed.
Hi Sirena many thanks for your reply and reassurance. My Mum has often complained of being lonely and also wants to go home when she’s actually at home so rationally I know it’s the right thing. Will let you know how we get on. Kind regards.
