In NC they can drop out at 16 without parental permission. However if she is being abusive to you, you can file charges against her at the magistrates office every single time. Its a pain in the rear but you can do it. She will be charged as an adult and for the most part for the first several times she will get slapped on the wrist with probation and fines and told to behave but if she doesnt get her act together they may stick her butt in the teen section of the adult jail. Now if they do arrest her for her charges, you are under no obligation to bail her out at any time. You can leave her there until the judge lets her out. Of course, she will get out long before she is 18 and she will come home but then you just keep doing this over and over again unless she shapes up.
The only other thing I can think of is to contact either NC baptist childrens homes about the program they have for teen girls and see if she would qualify for that or social services. Either of them may help.
