Poor Majesty! If she is acting lethargic and hasn't eaten in four weeks, I'm afraid she has a serious problem. These symptoms are unfortunately very vague and could be caused by almost any type of illness, so it's impossible to say what might be wrong without being able to examine her and do some testing. I would recommend taking her to see a vet as soon as possible, since I'm concerned that she may have quite a serious illness. Your vet can do blood work and x-rays to help diagnose the problem and get her started on appropriate treatment.
