Dear Dr. Litman,
I will never forget what you did for me. During a very trying time, you cared for me with much devotion and you brought back my faith and hope.
Thank you for doing everything possible to keep me alive. Thank you for being so caring, understanding, and charming. Without your support I would not have been able to overcome the disease. Thank you for not letting me give up.
In my case, thank yous are almost meaningless, since I will remember you for giving me another chance at life.
With great appreciation,
