Is it normal that my mom calls me a fatass?

We are very poor and my parents are like retards who don't work and collect this government money. I'm 17 we barley have well we don't have any food we have like cereal without the milk or oatmeal not even soup and we get pizza sometimes I don't live here but I do for like 2 weeks at a time and I stay here for school. So I usually don't eat all day unless it's cereal without milk like Cherios or something. And when me and my parents get into arguments my mom usually calls me a fatass a couple times she also calls me it when I ask for something to eat after I diddnt eat all day I do everything I can not to be here I'll stay with my grandma or camp in the woods for a couple days at a time beside this lake where I fish for my food. I'm a little fat you could say but its mostly water weight I drink a lot and no I don't mean beer I drink beer occasionally but it's mostly lots of water and soda.. Is it normal my mother calls me a fatass?
