I don't know how to comfort you except to let you know that you have shown me, by example, a better way. I am sure that your sister shares the heroic qualities that you have shown us all.
I pray that God reveals himself to you and Donna and that his mercy and comforts fill you. I wish I myself could help you and Donna in some manner, My prayer for all of you.
Love,
Rick in Ashland, Missouri
