How the world views my mom

I held a party of a few friends at my mother's yesterday and their reactions to her was one I was very used to. They do not see the cruel woman that I have grown so used to seeing. My mother wears a mask. One of the more common ones, is that she makes people like her by seeming very nice and likable when they are around. However, the real underneath likes to bend people to her will in order to create the world according to her. For example, with me, she allows her true colors to shine through. She is cruel, not caring that I have my own wants and needs. She loves to play the 'You are still a child, because you are not eighteen yet.' card quite frequently. My friends do not see how she subtly harasses me, by pointing out how I'm a idiot as compared to her and making me look like a child to her adulthood. She exercises her power as a adult to try and force me to bend to her will, but I see through this because I have dealt with this as a child. However, this does not allow her to do these things. It is wrong. I have rights as a human being at the very least and she believes that she owns me and treats me like a slave.
