I am sooo sorry.
Wow this is deja vu for me. I had the exact same thing happen last year so I totally understand. I completely feel for you about making the decision to keep her medicated or finally have to put he down. I also got results that were extremely high and also did 2 days if fluids which didn't help. I then decided to bring her home and give her lots of meds and take her to the Vet every couple days to get fluids. Nothing helped of course. The only option was a kidney transplant which is really expensive and not really an option when they get that sick.
My kitty only made it a couple more weeks and we had to also have her put down. She just laid around and we forced water and meds into her all the time and got so weak she couldn't even make it to the litter box or even stand up to go to the bathroom. It was just to hard to see her like that so it was best for her. The day she got bad like this was quick and immediately I took her to the vet but it was those few hours of knowing she couldn't get up on her own was very very hard.
My point is you did the right thing. I did what I thought was the best to keep her alive as long as I could and hold her and spend as much time with her before she got too bad but to see her like that was too much. It is now very hard to get those visions out of my head so I think you made the right move and not letting her suffer.
On a side note when I kissed my kitty goodbye for the last time I told her to come play with me in my dreams and show me she is ok so maybe that was your kitty's way of showing you she is happy and ok and waiting for you.
Here is a great poem that helped me when this happened
