I feel you, @bluefinstudios. We've just had another scare with my mum. We nearly lost her three years ago and she was in a bad way for many months before she miraculously got better and kept on living. But she's never been 100% after that so the thought of losing her is rather present all the time. My relationship with my mum is an unusual one that I can't even figure out myself so I don't really know how I feel about it, let alone how I will feel when her time comes. I have a feeling it won't be easy. It never is. Enjoy the time you have left with your beautiful mum. She is lucky to have someone to snuggle too.
Thanks, and good news on your own mum!
