I know running away is bad but what if their is no other option.?

i recently left my moms house who i was with all my life. she was the best mom in the world it seemed like, but she picked a child molester over me, point blank. She always moved me around from indiana to ohio and back and forth. But i mean she was an amazing mom she always cared for me when i was sick, one day i told my parents and they came and arrested my step dad because he is the one that did this to me. Now i live with my dad, and HIS WIFE, and she always did things with me illegal stuff, my dad found out and keeps blaming me, well there was a situation thats happening now and its the final straw, im 16 right now and i honestly cry myself to sleep every night because i hate having my parents pick people over me, this time i never did anything, my dad is really manipulative and HIS WIFE knows this and so she keeps on and since I "tattled" on her, she wants to make my life hell. I'm done with it, advice, dont even tell me im childish because theres nothing i can do.
