Youth welfare office but without a German passport?

Hey, I'm 14 (soon to be 15) and have been living in Germany for seven years. My parents are very strict and somewhat toxic. I was beaten and hurt my entire life until they stopped last year, so unfortunately I don't have any evidence of that anymore. But they're still very toxic.

My parents expect me to get no lower than a B-, otherwise I face severe consequences. I'm only allowed to go out with people who know my parents well and who also know them, and I'm not allowed to wear anything that "shows off" my body in any way. And by that, I don't just mean crop tops, but also my shoulders or any part of my legs or anything that's a bit tighter.

I often have panic attacks because my mother is always yelling at me and insulting me about everything, even if it's just something minor like me forgetting to empty the dishwasher. I also live in fear all the time because I'm emotionally abused every day and told things like, "You're so worthless" or "You're the biggest problem in my life."

I recently fell in love with a boy my mother also knows and knows he'd treat me well, but she's forbidden me from having contact with him and told me to cut off contact. They keep forcing me to take private religious classes, even though I don't believe in them. But I'm afraid to say so because they might send me back to my hometown.

I also get yelled at all the time and said really horrible things when I have these panic attacks. I'm constantly told that if I go out with this boy, or wear anything revealing, or don't get good grades, or contact the youth welfare office, I'll be sent straight back home. And that they'll lock me up there, and that even at 18, I won't have any say and can never move out until I get married.

All of this is taking a huge toll on me mentally, and I know that if I don't contact the youth welfare office, I'll continue to suffer severe emotional and possibly physical damage. Can I still contact the youth welfare office if I don't have a German passport yet? Or do I risk being sent back and imprisoned? Please help me; I'm slowly losing hope. And if so, can the youth welfare office help me move out?
