If she hasn't been eating you need to start syringe feeding her and get some food into her. Make certain she is warm enough and responsive so she doesn't choke.
As Kyouhai mentioned, she does need a lighting schedule which is very easy to accomplish. Also, is her cage a consistently warm temperature?
