LG- my deepest condolences on the loss of your best friend and faithful companion. She was a beautiful kitty. I'm sorry it ended the way it did, but the fact that you held her and loved her until her last breath is the way you both needed it to be. You both gave so much of yourselves to each other. There will never be another just like her, but if you decide to adopt again, the life you save will also save yours.
Big hugs to you. We all cry along with you.
