[katnip]

I had my old KissyFace (I did not name her) for 22 years.
When she died I cried for 4 days.
I think your kitty sounds like it might get better.
If not, just think how much longer and what a nice life you've given this little creature
By the way, I would let the other cats (the ones that love her) stay around her if they want.
Especially if she doesn't seem to mind.
I'll say a prayer too.
