I'm so sorry, Lut. It does sound like she is ready to go.

Yes, let her sleep on your bed if that's what she wants... anything you can to keep her comfortable. See if you can make her drink a little, even if you have to use a syringe, but give it very slowly.

Did the vet give her anything for pain?

Sending lots of comforting thoughts and kisses to Zazou - and hugs to you.
