Speak to an adult you can confide in about what you’ve seen. It could be a family member, teacher or youth worker, for example. They might be able to help clear things up and sort out your concerns.
If you stumbled across something online by accident, that adult may have some tips for how to avoid seeing that upsetting thing in the future. They can also help you find the report button on a site.
If you don’t have anyone you can speak to at home or school, there are services you can call, email or chat to online here.
These services are there to listen and help you with what to do next. They won’t try to stop you from going online, and you won’t be in trouble if you found the worrying content on a site you’re not old enough to go on.
