Adopted By My Brother!?!?!

Hi my name is Eliza Jay Anderson, I'm 13 years old. I live in Milwaukee, Wisconsin in the United States. I have 2 brothers, they are twins and 3 years older than me and their names are Andy and Chase.
We are called the 'emo' group at school, because of the music we listen to and the way we dress. I'm normally wearing band T-Shirts and ripped skinny jeans, I have black and blue hair and normally wear dark make-up and my hair down.
My brothers are very protective of me, they are my best friends apart from Alice. She loves all the bands I love and dresses like me, we share the same interests and most people would think we were sisters.
My parents don't like the three of us they try to hide it away from the outside world. My dad works for a building company called 'Drake-House' when he hasn't got work he's mostly drunk. He abuses us, but the boys step in front of me if Dad is about to strike a hit, they end up taking a hit for me.
