What should I do about this?

My parents have been divorced for ten years and seven years ago my mother remarried. She and my stepdad are sometimes verbally and physically abusive of me and my brother (who has mild autism and doesn't understand what they're doing is wrong).

On the last day of school, I wrote a story about a girl who was mistreated by her mother which was kind of autobiographical and I gave it to a teacher and I hoped the teacher or the principal would ask me if something was wrong. I felt guilty, I guess, and I didn't want to just tell, because it was hard for me, and I know it's stupid, but I wanted someone to ask. So on the last day of school, the principal asked, but my stepdad was in the office and I got scared and said nothing was wrong. I know that no one can help me if I didn't tell them I needed it, but I WAS SCARED. Later, I wrote the principal a letter so she would understand the situation, but I know I should have told when I had the chance.

When I got home to my mom's house, she freaked out about the story, because apparently the principal (whom I'd actually trusted) had told my mom about it despite me telling her specifically not to do so, and my mom told me to get out and go stay with my dad and never come back and I said I would and I did.

My dad said I could stay with him as long as I needed to, but then my mom said I could stay with my dad but she would keep my brother then. She got Social Services involved and tried to prove I was dangerous to my brother, but they told her to give my brother back to my dad part-time, but when I tried to tell them about the way my mom abused us, they didn't believe me. And now my mom's going to my teachers, especially a teacher whom I had a couple years ago who I have a really special relationship with and saying untrue and terrible things about me, like I threatened their lives and I'm afraid they believe it. My mom can put on the act really well, and if they've believed it for six years, why should they believe me over my mom now? She's gone to the school and gotten me in trouble before for things I didn't do and the school believed her!

My dad is trying to fight for legal custody of me, but it's not likely he'll win. I CAN'T go back to my mom's because I don't feel safe - she'll hurt me! And my brother's going back and forth like usual and I'm scared she may hurt him, or might have already done so. And my mom's threatening to go to my summer camp and make a scene unless I come with her or she'll do bad things, etc. I'M SCARED of her and my stepdad. Will the court actually force me to go back somewhere where I feel unsafe? Am I doing the right thing by trying to stay with my dad forever? I feel so guilty that I'm not going to be with my brother when he needs me most and at least try to protect him from my mom! And I even miss her a bit, because she sometimes CAN be nice even though she's usually not. What should I do?

Go back to school, and let the teachers know, that there is a good reason why you are living with your father and not your mother. Do not go back to your mother's if you feel unsafe. They will not hurt your brother, if they know that you are opening your mouth about the treatment you received. The courts will keep a good eye on everything that is going on. Do not be afraid to say what is really going on, your happiness is at stake. Your Dad is trying to fight for you, and the courts will listen to you, when it comes time for the final decision.

you really need to tell someone who will LISTEN and FIGHT for it,to help you your dad and brother,

Go to the school as soon as you can. Classes do not start for several weeks, but there is staff in the building. Ask to speak to a counselor. They are trained to handle things like this. While our kids were in high school, we took in 3 of their friends (from 3 different families) as foster children. The school counselors set it all up, legal papers and all. You do not have to stand alone in this problem. They can help you. Good luck.
