Depression.

Attack

I looked to see where the screaming came from and it was from a small girl, she was pushed onto the ground and was now getting beaten by an older teenage boy. He punched her, and all the people were doing was video tapping it. I walked over and screamed,"get the fuck away from her."
He looked at me like I was insane," get away from me you little bitch before I hit you too," he said pushing me away.
"No, I'm not going to let you hurt a poor girl for nothing," I said pushing him back.
He walked away from the girl and pushed me towards the ground, I fell pretty hard but got back up. He swung his fist at me and missed so I took a swing at him and hit him right in the jaw. As blood dripped down his chin he swung again making contact with the side of my head and making my vision blurry. I suddenly saw nothing but darkness as I fell to the ground.
