IF he does press charges....upon arrest, you have the RIGHT TO ATTAIN A LAWYER, and since you are a minor with no money, you will qualify for legal aid and then you can ask them to have children's services remove from your dad and stepmoms custody and have you placed elsewhere.You can file neglect and abuse charges, and since you have an aspergers diagnosis and the reason for all of this is because your dad is in denial and refused to give you treatment, he and that evil witch stepmom can both be criminally charged for neglect and abuse.YOu can also look at the possibility of suing them civilly for malicious prosecution and abuse and neglect once the bogus charges he presses against you are dismissed.
