We had exactly the same. My mum had a massive and disabling stroke 12 years ago. When she left hospital she was admitted to a nursing home, as she is completely paralysed down one side and largely helpless apart from being able to feed herself with her right hand.
She self-funded for years, which took the proceeds from two houses and her entire savings. When the council had to take over the cost, they decided that she would have to move to a flat in an extra care block.
My brother and I were totally against this, especially as they said that in addition to having four carer visits a day, she was likely to need family support. I live two hours away, and my brother has health issues, as well as constantly being emotionally abused by her all his life. We both said we could not support her, but the council went ahead anyway.
The carers have an office down stairs, and they do all her personal care. They also do her shopping, but of course only prepare the most basic of meals as they don't have time to cook from scratch.
Fortunately my mum likes her own company and didn't have any social life at the nursing home, as she has her marbles and most of the other residents didn't. So she's quite happy in that regard. But her care and her nutrition is nowhere near as good.
This was supposed to be a cost-cutting exercise on the council's part, but we've seen the bills and her rent and care plan come to more than the nursing home did. It's insane.
