Repression

Suddenly you begin to panic again, and you start to fumble with Mom's body which has obviously been violated with the ripped up clothing and all. Of course even without that evidence, you standing over her with your pants off is enough for your sister to draw her own conclusions when she walks in on your attempt to make things "normal" again.

Your sister won't help you with this. Instead of looking like a sympathetic emotionally abused victim who was driven over the edge, you now look like a sick homicidal incestuous necrophiliac (And you are)

She screams and runs out of the house before you can stop her. You know she's going to get the police and you can't say you blame her. You're revolted by your actions. You throw up.

You don't know why you did the things you did today, but you're sorry you did. You begin to cry and scream as your tortured mind attempts to make sense of the situation, up until the time the police take you away.

Eventually it's decided you should be in a mental institution, it doesn't matter to you though since all you want to do is die.

Another day arrives, you wake up in your cell and feel torment...
