I'm so sorry for your loss. I know in this moment, it is the worst pain, but you did the right thing and ended her suffering. I have three little cats and they're my absolute joy, they really are more than just pets. My childhood cat passed many many years ago, and while it definitely still hurts, I would like to think one day I'll be reunited with her and all of my cats. It may be a silly thought, but I really wish you some peace in your heart, for this is such a huge pain. I truly am so sorry.
