I recommend to stop handling her (except for cleaning) until she starts eating regularly.
Try to get your warm side to be around 90 and your cool side to be around 80 (so like satomi325 said, lower warm side and raise cool side).
Ensure she has 2 IDENTICAL hides, one on the warm side and the other on the cool side.
If she's in a tank, try blacking out 3 sides of the tank to make her feel more secure.
