I'm very sorry for your loss. It's a horrible place to be - I still miss my old lady, my cat that I had from one day old until almost twenty years old, and she's been gone for a couple years now. But she had a good life, and she didn't suffer in the end - and that's the important part. Thank you for being a good pet owner, giving her a good life, and being responsible enough to let go for her own good. Too many people don't know how, and think of their own pain before that of their companion. Hats off to you, Rob.
