Pet Snake Worries :(

Things that instantly comes to mind is like Fishbone said, sometimes they just want to be left alone, and the temps/humidity of the enclosure. Second thing that comes to mind is where is her enclosure set up? Is it an noisy high traffic area of the home? That kind of thing will stress a snake out more than almost anything. I would try to see what happens in a couple of days or move her to a more quiet secluded area of your home to see if that helps at all.
