Here are my thoughts.
1) Where is your thermometer/hygrometer to measure temps and humidity?
2) What are her temps and humidity?
3) Did she ever feed for the breeder you got her from?
4) She needs two small snug hides like the plastic flower pot saucer one I have in this picture - entrance cut out with solder wand
There's really a baby under there:
5) Don't dangle prey directly over her - that's very intimidating to her - instead, put the live prey in the enclosure at the opposite end of where she is and let it wander around and allow her to ambush hunt it from the smaller, tighter hides suggested above.
6) How are you heating the enclosure?
7) Fill that tank up with loosely crumpled newspaper to help her feel more secure and after a week, drop in a live hopper mouse and walk away. Check back in 1/2 an hour - hopper mouse should be gone.
8) Start to gradually "wean" her off of the newspaper by removing a piece or two every few days.
