I'm SOOOOO FRICKEN SICK OF MY STUPID MOM!!!!!?

Ok she is constantly telling me how I look anorexic and gross. I eat all the time and I never have been or will be anorexic. I use to be 120 pounds and I dropped 105 ONCE I BECAME A VEGETARIAN!! My mom is overweight and she is constantly feeling "warm" so she never turns on the heater in our house so I'm always carrying around a blanket cause im freezing, she does not care that i'm cold and I have to lug around a blanket everywhere. She told me i looked gross earlier cause of my weight. I told her it damages my self esteem and she claimed she never said that which i know she did cause I about cried over it. If she keeps up her ways I don't think I'll ever talk to her again when I'm 18 which is in 4 months. And before you all say "i think she is sick of your attitude too" If that was true why won't she let me move out with my boyfriend? She said she would call the cops if I tried to leave. Some people should not be mothers and I think she is one of them I wish I had a better mom
