Ok, I need serious help. My home is not a home anymore. My 15 year old step daughter has an 18 year old girlfriend who has all but moved in. My 16 year old step son smokes and plays XBox. Neither do anything to help out around the house, they don't clean up after themselves, neither goes to school anymore, the boy sleep cycle is approx. 30 hrs. long; ie he is often awake through the night keeping everyone from getting a good nights sleep and has a no issue with taking whatever he wants from anyone elses room whenever he wants.
