Sixteen-year-old Darren used to be a bully. He picked on other kids and called them names.
Darren had lots of problems at home with his mum, but now his life's really changed.
In his report he tells us why he was a bully and why he'd never do it again.
"I went round picking on people, hitting them, getting into fights, ripping their clothes.
I could see them getting frightened and sometimes they'd cry but I didn't feel pity.
Problems at home
Mum drank (alcohol) and beat us. I took it out on others.
I had loads of stress. I wanted to let it out but it was wrong to do it to other kids.
