Only other thing I can suggest, and you would really have to think about this....would be calling your local Dept of Human Services, Child Protective Services yourself. Understand you would NOT be emancipated, but likely placed into foster care until you are 18/have completed high school.

In order to be emancipated, you have to be able to work, pay your own bills 100%, and maintain good grades. And no living with others, it has to be all on your own.

As Aardvarc said, you have very mature reasoning. Good luck to you.
