I know exactly how you feel. I had a little BLRW that got squished and was the only survivor. He lasted weeks, he would sleep on me for hours, and sit on the desk and watch me type. Finally one day I was petting him, and knew it was his end after hanging on so long. I held him and loved on him until the end when he finally died in my hands.
Goodbye my little friend. Miracle.
I'm sorry for your loss.
