I had various reactions in my extended family from what a wonderful thing, we're scared for you, you saved my day's life, to you are an idiot. In the end I donated because my brother needed it, I could help, and I thank God that I did. Some of my in laws still think I was an idiot. It does not matter. What did matter occurred, and worked, and still works, going on our sixth year now.
Good luck to you!
