Mom issues

Melodi • 19 and in college
I am 19. My mom is always belittling me about everything. I was 250 lbs in 8th grade and she used to pick on me so much I practically starved myself. I lost 75 in 6 months. I know it wasn't healthy. I gained weight on the past few years and yesterday she told me the only reason I came home (since I am college) was to gain weight. She always mention that my hips are spreading and my arms are getting fat. I am tired of her picking on me. I never want to be home, let alone have a conversation with her. I have gotten so insecure with my body that I hate myself. My boyfriend tells me I am beautiful and he gets mad when I say I am not. How do I get out of this insecure bubble I have? Please help!
