What do I do...

ok I know my mom works and all but I never see her… even when she’s standing infront of me. I’m almost 14 and since a was about 8-9ish my mom stoped talking to me like not compleatly swe have conversations like.I ask how her day was she says “fine your’s?” I say good and she turns and walks away or goes back to her stupid games on pogo.ca and doesn’t hear a word I say or even notice I’m still standing there. When she decides to notice me she’s yelling at me she calls me fat and lazy. At the diner table were people are supposed to talk to each other the conversations always and only consist of her my brother and my dad I can barely ever get a word in, And then at parent teacher nights when my teachers say I’m quiet in class and don’t raise my hand much she says she can’t belive it because at home I never stop talking…(I barley ever say anything anymore :S) I just don’t knbow what to do anymore.
