Please answer, all answers appreciated! I need help?

You might remember my question on my parents' abuse...its happening again. My mum was being really nasty and then my big bro said to her, "Get out of my room," And i muttered "Good on you,". She didn't punish my bro for saying get out, but she took away my i-pod and she rang up all my relatives in Sydney and said she won't be going with the rest of our family there for the hols cause i'm such a c***. My bro is smirking and laughing. I don't wanna go through it all again, i want my i-pod back and a normal family! My brother just told her to shut up and she does nothing-she only hates me. If i was gone they would be a perfect family. I'm so scared and i used to punch myself to cope with the pain, i keep getting the urge 2 do that.
PLEASE HELP.

My brother is older than me, and i'm not making a big deal for nothing-my dad pegs stuff at me and my mum is absolutely mad. In her eyes i'm a tart, ****, b****, C****, F***head, everything. I know 'cause she tells me.

i'm sorry, i don't know what to yell you. but i hope things work out. maybe you can talk to social services. idk
