I did not donate bone marrow, but I have made a life saving donation. Four years ago last month, I gave my husband a kidney. It is something that I do not regret. My husband called me from ICU the evening after our surgery was something that really stuck in my mind. My mother had gone to see him and came up nearly in tears because of the difference in him. The first thing she said was that he had color, and then he had grip strength. Many tears of joy have fallen since then. I really hope that it is something that you are able to experience. Good Luck!
