I still don't think you have anything to worry about, but I agree to taking her to the vet if only to ease your mind. Ditto on only disturbing her to clean/water/feed. Maybe also try covering her tub with a dark cloth for awhile and see if that helps. Again, just keep offering once a week, leave it overnight if she refuses. And make sure to remove any uneaten feeders first thing in the morning! If you're really getting desperate (as in many weeks without feeding), you can again try live with a harmless rat pup. No worry about biting or scratching
I think covering the tank will definitely help as well. Mine is covered on 3 sides with a dark towel.
