I am sorry you are in this situation. One thing I will say is there IS such a thing as anti-nausea medicine. One of my cats took it for a while. It has been a while, so I don't recall the name, but he did take it -- it started with an "R", I believe.

I fear without vet help, she will not be with you much longer.
