Liz, what can I possibly say???
I have stood where you are standing, and I shall do so again, possibly soon, with Rabbit, and I know how your heart aches.
She is waiting, now, the door is open, I think it may be up to you to help her go through, and that is the hardest thing of all, and yet we know, when we take on the joy of these creatures that there will also be tears.
This is not something you have to do alone, we are all there with you, whether you can see us or not.
Gramma is not alone, either, she can already see where she is going, and I think she may be ready to leave.
Part of her will always be with you, but you have to let her body go.
God Bless.
