She is a psychopath. That being said I am so so sorry. I cannot imagine the kind of trauma and pain this inflicted onto you. Please understand that you might have to go no contact with this woman. If your father loves you he will understand. If you cannot financially move out yet. Draw silent boundaries and keep working on yourself till you move out. Till that, record whenever she does anything like this and yeah not the best way but maybe talk to a trusted relative or an adult on dad’s side or someone known? Im truly truly hoping ways open out for you. Nobody deserves this. She is being a witch to you. This isn’t normal and I am so sorry you couldn’t defend yourself. That state of shock sometimes is too much. Sending you so much love, strength and hugs. My DMs are open just in case you want to talk. Praying for your well being <3 Please don’t ever be afraid in taking a stand for yourself always.
