Just as Robert mentioned, antibiotics kill off ANY bacteria in the body, even the good stuff. It doesn't know better It's best to wait until the antibiotics are gone to try to feed, so the snake can slowly start building up the good bacteria in their gut again. Smaller meals are better, and if she was on large adult mice or smaller rats, try a few small mice the first few feedings, making sure she doesn't regurgitate anything. Keeping her stress level down is the main concern.

You're doing an awesome job taking care of her. I'm with Joanna on this one, sending many well wishes your way
