Abuse can mean a lot of different things.
It includes neglect, physical abuse, emotional abuse and sexual abuse. It's not always easy to tell if you or someone you know is being abused. But the important thing to remember is that no-one has the right to hurt you or make you do anything that feels wrong.
If you, or someone you know, are being abused, the most important thing to do is talk to someone about it. You should speak to an adult you trust. Or you can call:
