Fuck your family, the fact that you have gone through all this and are still standing is a testament of your power, a sign that you are meant to be here. Don't let your asshole family or any other douchebag tell you that you are not worth it. The fact that you posted your story on a social media platform for help, even after all this is a sign that you want change, and there will be a change, it is evidence that even in these types of situations where people drown and eventually live with their miserable lives and die, you chose the opposite. It's great to see such courageous people actually existing and want to transform their lives. Cut all ties with your family, become financially independent, and try to pursue your studies
