It's still your mum, whatever age she is when she dies. I do have sympathy for that aspect of it all, it's never easy. As someone who lost both parents in my 30s, I always envied those who had decades more time with their folks - but it's still a deep loss.
Sorry to hear what you went through. I’ve friends who lost both parents and they say the second one is so much harder to take. Losing that final connection to your childhood. I don’t really want to start a pity party about an extremely privileged man but he lost both his parents in fairly quick succession. So his pain right now will be very real and acute.
