Is it just me or do other people feel this way too? (read description vv )?

Sometimes my family calls me fat. I know I am. But it just makes things harder on me and makes me self conscious. Then I stress out every morning if I look okay for school and other things. I feel like when they don't say that stuff about me I do better but when they do I tend to do worse and eat more. Is this how most people are or is it just me? Because I'd kinda think being upset about what they're saying to me would make me quit eating or something. Please be sincere. I'm a young sweet girl.
