"Hello sweetheart. This is you as an adult in the future, coming back to answer your prayer. You know the prayer where you asked for help and to have someone save you from all the abuse? I'm here to tell you what to do. Now don't be scared - I need you to be a brave little girl okay? What you have to do is gonna seem real scary and you might not know what's going to happen but you will have to trust me on this okay?
When Dad has gone away for the weekend, I need you to do this okay? I need you to call the Police and tell them everything that Dad did to you. Can you do that for me sweetheart? Be brave now and tell the police everything that's going on and everything that's happened. He's not going to hurt you or Jim or Mom. He's just being a big bad meany trying to scare you.
Now when you finish telling them what's going on, tell them that you want someone to come get you because you don't want to be home when Dad gets home. Tell the Police that you don't want to be taken care of by family that you don't trust them and you want someone that will take care of you and won't hurt you. Don't back down from that okay?
I know that you don't understand why I'm taking you away from all the family. But I will tell you this, as you get older, the family will keep on doing things to you as you grow older. We won't get into what. Only know that you deserve to be in a family that will love you, take care of you, and will never EVER hurt you.
I love you sweetheart. Now go... and don't forget anything I said okay? Don't back down off anything you say. No one can hurt you any more!
Love,
Your Adult Self
