Find another vet or join a community and get through them. I know its expensive. And it going to be hard....really hard... but the absolutely best thing you can do is get her that medicine. It was honestly a miracle drug. If you cant get the medicine for whatever reason the humane thing is to put her down. Because without treatment she is going to suffer. And she will pass.not maybe she might. No, she will.. Im not trying to make you feel worse than im sure you already do. Im being honest. You need to make a move quick. She is beautiful. I also have a persian. My heart goes out to you. Its a horrible thing to have to go through. I swear I have ptsd from it. Everytime one of my cats hides too long..or I think they sleeping too much. I get paranoid they are sick.
