You poor thing, tell an adult that you can confide in. People like that can easy manipulate victims into keeping secrets, but you have to think you might not be the last.v
I'm 14 and I can't imagine what you've been through, you need to tell a doctor and an adult to get him locked away.
Also there are child lines in which you can get supports! I wish you the best, you're an amazing soul.
Remember how strong you are.
