Tbh I think the care system is completely broken and the expectations of many it, and certainly the government are wholly unrealistic.
50 years ago, people married and had kids younger, and most women were SAHMs or worked very part-time. Families often stayed in the same area for generation, divorce was less common.
For those who lived long enough to become unable to look after themselves, there was frequently a handy DD or DIL on hand.
We now have an ageing population, people starting families later, moving further afield, divorcing and starting new families, and most women work.
For those who are single parenting as well as working full time, elder care is a minefield practically, never mind the emotional impact. Or the women who had kids later and are juggling primary aged kids, elderly parents, work and the menopause.
With people living longer, many family carers are in their sixties themselves.
None of this is OPs fault of course, but a little empathy and understanding wouldn't go amiss.
The system is no longer fit for purpose and needs a radical overhaul, something sadly unlikely to happen any time soon.
