It's always especially sad to see a dear person who has meant so much to us pass on. But I personally believe there is life after death. She has lived a long life, and I hope folks have learned from her example of caring. But remember that she is likely suffering and will be healed from her broken-down body when she passes into the next part of life. I can't say that you won't see her again one day in the future.

Happy Birthday, dear one! Please keep things in perspective and don't let this sad news ruin your special day. She wouldn't want you to, I'm sure.
