Welcome to YT!
Poor baby! She's a little scared right now. Try and keep her on the same food as before. Make sure she's drinking water and her gums stay pink. As far as not eating anything, maybe try a little chicken, cottage cheese or plain yogurt.
If she hasn't had anything today, I'd call her vet just to be on the safe side.
It might just be adjusting to her new surroundings, but 3 days is a little long to go with out food.
Please keep us posted, and again, Welcome to YT
