problems with parents

i hate my family. they think they could make fun of me and not hurt my feelings. yesterday, my parents kept saying we got bad hair cuts because we never do our hair like curl it or straighten it. they say combing your hair is not doing your hair. my dad never had long hair and my mom only cares what other people think not what she thinks. then later that day i got in trouble again and this time it was their fault. they kept making fun of me so i through a piece of bread to my older sister, jenny. i walked a way but my dad called me back. if i could i would have have kept walking. he called me over but then i saw something on the floor.
i stopped to look at it and then my dad yelled: SIT DOWN AT THE TABLE NOW!!!
i had to sit next to him which i didn't want to. i walked to him like a snail. i know that was annoying him but i didn't care. he was being a jerk to me. only me. he never corrected my sisters when they called me fat. I'm chubby, not fat. the chair was too close to the lag so i tried to scoot it closer to him which i didn't really want. he grabbed my arm and pushed me down to the seat.
dad: WHATS WRONG WITH YOU. YOU KNOW, YOU HAVE BEEN HAVING A BAD ATTITUDE LATELY. AND YOU KNOW WHAT , I DON'T LIKE IT AND NO BODY ELSE HERE DOES! i only got mad that morning.
i don't call that "lately."
then my mom asked me : whats going on Amanda? is everything okay?
of course everything is okay its just that my dad always and only picks on me and i don't like to be bullied. that happened last year in school and i put an end to it a long time ago.
then today i went to go shop for my graduation dress for my 8th grade graduation with my mom and my 2 sisters. i chose the first 4 dresses i liked and quickly tried them on. my mom didn't see the first one but she had to see the rest or them. she picked this black, short, shoulder-less dress which i didn't liked but i tried it for her. i had to chose out of the five dresses and i chose this tannish dress that looked really good on me. when i came to my mom wit it she looked away.
mom: the other one looked better on you than that and that one looks more casual than formal.
i didn't want to say anything because i have been silent the whole day because i knew if i said something it would be wrong. she kept rambling on how i made a bad choice. when we got to the cashier my mom said;
mom: you know your dad won't like that on you. you know your dad.
i put my dress on the counter and got it. i didn't care what she said, it was my graduation, my dress, my choice. then she started to say some stuff that i can't say on my blog. well that is it.
