Sometimes things that happen in the world can make us sad, anxious or confused.
It's important to remember that upsetting stories are in the news because they are rare - they don't happen very often.
But what can we do when the news makes us feel this way?
If the news has upset you, talk to an adult you trust about it. It's important to share what is troubling you.
You might want to talk to someone at home, or you could speak to a teacher at school.
It could be something that your classmates are thinking about too, so your teacher might decide to have a discussion in class about it so you can all understand things better.
It's important to remember that being sad, worried or angry about awful things that happen in the world around you is okay and perfectly normal.
You won't be the only one who feels that way.

Doing things that make you happy can help you to feel better.
Watch your favourite film, take your dog for a walk, play football with your friends or read some of your favourite book.

Don't forget - terrible things are on the news because they are rare and do not happen very often.
Although people are spending a lot of time talking about it, it is still very unlikely that events like this will affect you or your family.
The most important thing is that if you are feeling upset, don't keep what's troubling you about the news to yourself.
Talking to an adult about what in the news is worrying you can help you to understand what is upsetting you, and help those feelings of sadness, anger or confusion to go away.
