Blah i swear my mom hates me?

yea so i got a pretty sucky relationship with my mom. I swear she hates me. like 80% of the time shes yelling at me. If i have friends over she'll talk to my friends and be like "yea i wish sarah was like you. I wish sarah did that" and shes always telling me all these things she wishes i would change. Shes called me fat numerous times and shes ALWAYS yelling. I hate when shes comes home because ik shes just gunna start yelling. My dad doesnt like the yelling so he pretty much just walks away and ignores it. Whenever anything goes wrong they blame it on me. Sometimes il go upstairs and do my homework and i can hear my mom downstairs complaining about me. I get straight As and my brothers practically failing but then i bring home an 85 i get yelled at. I swear she has anger management or soemthing. When shes mad she slams things and shes broken doors, the fridge, dishes etc. So like what are some things i can say to her? I mean we dont have a relationship any more. I dont feel like i can talk to her any more without feeling really insulted and just wanting to cry. So wat do you guys think i should say to her?
