And now my Dad has the same diagnosis.
Dad is much older and when his death comes, he'll have live beyond the average life expectancy, but I haven't recovered from the last ordeal yet. People use the word trauma too easily IMO, but dealing with that (during Covid lockdowns) changed me forever, and I don't know if I can face it again.
Fwiw Mum will want to do all the caring without help (DH did have carers) so in theory it won't fall to me, but mum is old and frial too. DSis will have lots of opinions on how Dad "should" be cared for, mostly correct and involving spending money, which I'd be all for, but Mum and Dad won't, and DSis lives 100s of miles away, so won't t be able to actually "do" anything.
I feel like crawling into a hole....
