I hope you don't mind if I join this thread. I can very much relate to the challenges and emotions expressed by PP here. My DH is 95 years old living now in a care home. He is no longer mobile, struggles eating, is now registered blind (though he has some vision) and increasingly muddled. He was never very cheerful his whole life and now likes to moan or complain about the staff and is paranoid that they are against him for some or other reason (like because he's posh and went to Oxford university). We are not posh. And the staff are professional and kind. He refers to staff as servants and described one Asian care worker in his 30s as the brown boy he nominated to be a prefect. No malice just confused. He comes up with lots of weird ideas like the mayor visited one Friday night at midnight and he was left out of meeting them - a surprise to him as he really ought to be chairman of the home.
I visit every Saturday and try to focus on cheering him up or distracting him - I tell him my news and sometimes read bits of the newspaper to him or discuss historical events/battles, maybe read a bit of a poem to him. He's not easy to distract from his miseries.
I am lucky to have sisters who also visit and take numerous calls from him - because I work full time he thankfully doesn't often call me.
His quality of life is poor and he always tells me he'd be better off dead. He says he's surprised he's not got better since living there..... Apart from going to hospital he has never left the care home since arriving 3 years ago. I care about him and apart from holidays visit him every week but it will still be a relief when he goes. It's no way to live.
