<human>: Give me a shortened version of the text

My brother is turning 14 in two weeks. He just started High School last week, and guess what. He still sleeps in my mother and step father's bed. He has no respect for either of them, cursing at them, calling them names, hitting them when he is really angry. 

But even with all that, it's not the worst part. The worst part is that my parents do the same to him (of course, it's where he learned it). Every single night there is a fight about something. Whether it's my mother's immaturity and inability to communicate, my step father's quick temper, or my brother's disrespect. 

Every single night. They all need help and would never seek it. It tears my heart apart to be here. My mother thinks she knows how to be healthy but doesn't, there are no snack, healthy or unhealthy, and all our meals are too large and they all eat huge servings, and complain when they are told by doctors they are overweight. 
I can't stand living here, but as of right now I can't afford to leave. I could go live with my father, but he lives with my sister who I don't even know, and who is a complete bitch. She is a hoarder and the room is filthy, which I would have to share with her. The house is unkempt because my father can't keep up with my sister's mess. It's almost as bad as over here.

I can't stand living here because everyone is a child and no one speaks to anyone with respect, I've tried so many times to teach them how to communicate with each other, but they don't learn because they don't want to change. They love the fighting. Sometimes so much so that it starts in the morning. Normally there are multiple fights a night, always simple, but always blown out of proportion, loud, and toxic.
<bot>: My 14 year old brother sleeps with my parents and his lack of respect and my parent's immaturity causes loud, cruel, and aggressive fights daily.
