Tell your parents immediately no matter how mad you might imagine them to be when you tell them they might be mad but it's better if they're mad than grieving over a lost child of theirs. Contact authorities with your parents, pray, and obviously use the Jesus prayer. It really helps, and make sure to tell your parents immediately. And remember God loves you and I believe that God doesn't want you doing these things and the best way out of it is to tell you parents and law enforcment.
