Prayers from here for your sister. I so hope I can put into words what I felt reading your post. Not many of us impact the lives of those around us in so positive a way as she has yours. Be sure and let her know, maybe even let her read your post, it may give her the added strength to beat the cancer, and at the very least she'll know she made the world a better place by being alive. I'm not sure that many of us will be able to say that we have done that, and she may not even know just how wonderful and special she is.
