Newsround wants to do a new report on bullies.
This time, we want to find out why some kids become bullies, what their experiences are, how it makes them feel, and why they keep doing it.
If you are a bully or have ever been a bully, we want to hear your story.
We don't want to identify you, so no-one will know that it's your story, but we do want to hear about your experiences in your own words.
If you're are interested, get in touch with us.
