How do you get your dad to stop abusing you physically emotionally and mentally?

It's not up to you to stop your father from abusing you physically and emotionally. His abusive behaviour is not about you; it is not a reflection of your character. It is solely about his own mental and emotional state. Your duty is to get away from the abuser, to find a safe haven, and to report him to the authorities. Let the courts and the healthcare system deal with your father. It's not your fault, nor your responsibility. Your job is to get out of there alive.
