Repression

Exposing your sister's cheating cad of a boyfriend was the right direction, but you definitely went the WRONG way about it.

Butch and his friends laugh at your attempt to convince him to confess to your sister or you'll do it.

They beat you and humilate you, then run off laughing. In a cruel twist you get sent to the principal's office again where he's less flexible. He assumes you're a trouble maker and suspends you effective immediately. You don't get a chance to talk to your sister, she and Butch take off early for some party. When your Mom gets home, your sister's run away event and your suspension put your Mom back in her usual hard ass mood. She screams at you and says your sister isn't her daughter anymore, can go to hell and stay there because she isn't welcome here anymore.

You've failed. Your attempts have been futile. You might as well not tried at all. You were the only one who really cared. You just thought that maybe if you had a more stable home life, you could feel like a normal person, but that goal is lost. You go to bed.

Another day arrives and you feel nothing...
