So basically, my dad is oriental and my mum is english. They have three kids, me, the oldest, my brother, and my sister

I look like my dad, my brother and sister look like my mum.

My sister and I clash a lot, and she tends to call me names when we argue. And she always chooses really really hurtful things that she knows are things I have issues with. It's a pretty common thing now, and my parents can only do so much about it.

I came downstairs wearing a skirt that came to mid thigh with some tall platform wedges and she called me a slut and then refused to apologise until my parents made her.

I got dressed up in my prom dress to see how it would look, and she was constantly bringing up how big my butt looked and how small my boobs were and how puffy and dark the bags under my eyes (this is after her phone going off kept me awake all night)

And the other day, we got into another fight, caused by me asking her to move over a little so i could sit on the couch, and she called me a chink.

My parents have both told her off and punished her, and she still hasn't apologised. She acts like nothing happened, even when she knows how much that hurt me.

I just don't know what to do. She's my sister, and I love her and she's only 11, but just...

I don't know what happens in this situation, because nothing my parents do makes it any better, she just resents me more and calls me worse things.
