Sad to hear your news. Grannies are really important. I had only the one, and I was the apple of her eye (don't know why? I was a rotten little brat, really).
She was encouraging too; a nice offset to my father. I drew her a red dragon once - in honour of her Welsh ancestry - of which she was really proud. (Wish I'd paid more attention at the time.)
Let the sadness be there. honour her memory.
