This is such a sad sad thing. I'm so sorry Kelly for you and for David. There is never a good time for something like this but I know it had to be especially hard on you since you couldn't be with her.
You gave Livvy a wonderful home and stuck by her through so much. You were a blessing in her life. She now has eternal peace and will be watching over you now.
Godspeed sweet Livvy. You will be so missed by so many.
