Baggs I think the OP has talked about this with her family, but they are continuing to pressure her.
If it was a case of you selling up a property and buying a more manageable one near your family, then I think that would be worth considering.
However, you are in sheltered accommodation, with the security that comes with that (although I believe in some cases this does not confer complete security to stay where you are but I may be wrong. I just remember that my granddad, who was in sheltered accommodation, was pressured to find an alternative because he became less able to manage and annoyed other tenants with the high volume on his TV and other issues). Having said that, private rental is a minefield - you will not be protected from rising costs and you will not have security of tenure. As another poster said, it may be possible for you to obtain sheltered housing in your family's locality. Would that appeal to you more?
I have heard several stories where older people have moved to be nearer their families and haven't seen them anywhere near as often as they had expected.
I do understand your family's dilemma. My Mum was in her 90's, with very poor sight and hearing, but she would not contemplate moving nearer us, even though she was more or less "marooned" in a village where there was little support from neighbours, except from one older longstanding friend who was marvellous. With a Power of Attorney I organised for her to have assistance in the morning and evening - administering eye drops, getting a drink/snack, etc. This wasn't really enough support but she was very anxious about spending too much and I did not want to upset her. On reflection, this was a big mistake. I should have just bought in more care and lied about the cost. I visited her each week - three hours each way on public transport - but I realise now that I should have done much more and feel very bad about it. Children feel guilty that they can't do as much as they feel they should so I do understand your family's position.
It is a very difficult situation, and I can understand your family's concerns. In the final analysis, though, it should be your decision, particularly as you say you have sufficient funds to buy in assistance if necessary.
