I have been a long distance carer (due to living overseas), first for my mother, and then later for my father. As an only child, it all fell on me, and it meant being away from my husband, and older children, for several months at a time. I can honestly say that it was one of the hardest things I have ever had to do in my life, both physically, and mentally. The stress and strain I was under was unimaginable, unless you've been through it yourself. I loved my parents dearly, and we were always very close, and, if I had to do it all over again, I would.
However, knowing what kind of stress I was under, I would never expect, or want, either of my children to have to go through what I did. I would much rather sell up my property and live in a care home. Living closer to them would be preferable, in order to have social visits, and contact. But I wouldn't want them to have the burden of caring for me. Social visits, collecting shopping, or taking to the odd appointment, are one thing, but not the burden of physically caring for an elderly parent, who's needs usually become more demanding, both physically, and mentally, the longer it goes on. That's not what I had my children for. I know they love me very much, but I would never put them through that.
