I'm so sorry to hear about Georgia.
No one can tell you what to do or what is best for your family. Only you know this and hopefully have a little while to think on it.
When my Chelsea passed, I new it was coming someday due to her CT, but wasn't prepared for how quickly she went downhill. I loved her more than I thought was possible to love a dog. No other dog could ever compare. I wouldn't even consider getting another at the time because nothing could replace Chelsea and I was convinced I'd never love another pup like I did her.
I went 3 years without a yorkie, until both my kids, away at college, thought I needed company and bought me ZoE. I don't know what I was thinking waiting so long. I love having ZoE. I still think of Chelsea often. I had many years with her and have many memories that are often triggered by things I read here on YT. She'll always be in my heart, and now, so is ZoE
