@leahd, Good morning. I hope that my greeting finds the sun shining for you today.
I have located a discussion that I want to share from the Transplant Group Discussion. It is titled - "Letter to donor family: I'm not sure how to start" I have a deep respect for this member who bravely shared her emotional and couragious message. In this discussion you will find more information about writing your letter. The letter does not need to be lengthy. Let me know if you have any questions. You can easily access it if you click on the link.
