Answer
Don,
   If she is still eating, I would not worry. Is she gaping her mouth or possibly have mites? If she shows no other signs of illness, she is probably fine. Take her to a vet if she continues to be lethargic for a couple weeks. There are a lot of things that could be wrong with her, but the #1 sign is loss of appetite. IF she eats at least every 2 weeks (longer as she ages), she should be fine. What is the ambient and hot spot temp in her enclosure? Does she appear malnourished? Sorry for all the questions, but these will help me diagnose her current state.
