This. I bet she's just overstressed. Don't handle her at all! not even for pictures. Offer her food in a week and not any sooner. Good luck! Hopefully she'll eat for you once she settles down.
Another thing to consider is trying live mice to get her started. I know you want to feed F/T but if she was feeding live from the breeder, she may need that to help her jump start. Also, make sure you're heating up the mouse completely.
