What a beautiful giving gift she left while leaving this world; by being an organ donor. There are so many people who die before an organ becomes available for them. Her gift will make so many families rejoice in your sister's gift and her gift of life to them. My uncle had a kidney transplant several years ago. Our family values the donor for their gift of a kidney for him.
It was so nice that you were able to talk to her on her last night in earth. You and your family are in my prayers.
Peace and prayers,
