It's a weird situation where there is literally nothing that can be done. We're effectively waiting for Grandma to go. I know that sounds callous, but it's not meant to be.
The really scary thing about all of this, is that I was watching Mum at work this Tuesday, and I suddenly realised that she's not immortal... and that in time.... well, you know what I'm saying - and I have to say that it scared the hell out of me. :-( The following day, all this happened, and I got an inkling of what Mum is going through now - that scared me too.
I'm starting to not make sense, so I'm going to stop now.
I'll update again tomorrow.
I love you, Mum.
