Dear {Donor},

I can't thank you enough for your kindness. You have given me a second chance at life, and not a day goes by that I don't think about you and how lucky I am to be here.

I look at life differently ever since I received my transplant {number of} {months/years} ago. I am now able to {do things you couldn't do prior to transplant} and live my life to the fullest.

Thank you again from the bottom of my heart.

Warm regards,
