What has the vet done besides bloodwork?
Two weeks out and no better indicates that these vets really don't know.
Have they talked about exploratory surgery or is she too weak?
Placing a tube to feed her?
I think more can be done in the hands of a vet that is willing to try everything. If she is really at death's door, then you can take her to the emergency department of a specialty hospital or university. They can admit her and the internists should be able to help.
I'm sorry.
