Catty my heart goes out to you, I can't imagine what it must feel like, but she is in a better place, free of her pain and suffering like you said. You will be in my thoughts and prayers as well as your family. Your sister must have been so strong dealing with MS, it is such a terrible disease and it is great that her family was there to see her pass and im sure she felt their presence. Take care of yourself, and lots of hugs.
