Awful people will do awful things and can get away with it. You might need to get away from someone like that at this very moment. If you are aware that you're in a locked in abusive situation and feel incapable of doing anything about it, you should seek out help from people in your vicinity who are stable. I.e people who aren't awful.
You need to seek out someone trustworthy, dependable, who can help you to a life of independence or at least to get you away from whatever abusive relationship or environment you currently are in. This might be private citizens, organisation or government body depending upon where you live.
Remember, mental violence is violence, and no matter who you are, you deserve love, respect and dignity. You don't have to be alone in dealing with the consequence after the fact.
Deep and unconscionable trauma in repeated successions over years can manifest in personality disorders that could take decades to treat. Damage to the psyche is defacto violence and qualifies as such in many courts. Optimally getting out early is key, so don't delay. But remember: it is never too late.
Please don't wither under someone's shadow or fade into a pit of despair. Your life's light deserves to shine, and it can shine elsewhere.
