I am totally in shock

The day my family has waiting so long for is almost here. My sister got the call about the transplant. She is the back-up on the list but she could very well get the transplant is the first on the list is unable or their blood work doesnt come back that great. We will know sometime tonight if she will be getting the transplant tomorrow. We are trying not to get too excited. If may happen now or it could mean a little more waiting (she would be next). I am praying so hard that this is it. She has waited so long for this day to come. I dont want to see another day go by with her suffering the way she has.
