I went through a period of mourning when my husband started dialysis. I understand. But once we got through the first bit, and my husband started feeling better, it really became a gift that not only kept him alive, but healthy. I hope you find the same is true.
I have a dear friend who counted treatments for the many, many years her husband did dialysis. He got a kidney about 7 months ago!
Every treatment was a victory! Another day of living. So live each day, because it is a gift.
