Answer
 If you have had her for a year without cleaning the cage and without proper lighting, chances are she may have MBD, a bone disease, parasites, or both.  The first thing is for her to be checked by a good herp vet immediately.  You can go to www.herpvetconnection.com for one nearest you.  Second, clean and disinfect that cage, remove all old substrate.  Rinse the tank several times with boiling water after cleaning and washing with disinfectant like Nolvasan.  
 Since there are a wide variety of different skinks, I would go to Reptilerooms.com, go to the Forums, identify your species of skink and get up to date info on the care for that specific type of skink.  Books are almost always out of date as soon as they are printed, since new things about reptiles are being discovered everyday.
