Body image

Body image is what you think and feel about your own body. When your body is changing fast, looking in the mirror can sometimes feel strange. Lots of girls go through this.

Most photos on social media are carefully chosen, taken in good light, and changed with filters and apps. Adverts work the same way. You end up comparing your ordinary day with someone else's best picture. You can't win that comparison.

Bodies also differ. Height, weight, bone structure, breast size and nose shape mostly come from your genes. Girls the same age can look completely different, and that is normal.

• Unfollow or mute accounts that make you feel bad.
• Think about what your body can do: run, dance, carry you, grow.
• Don't say things to yourself that you wouldn't say to a friend.
• Value the parts of you that have nothing to do with looks, such as humour, kindness, curiosity and talent.
• Wear clothes that feel comfortable and suit you.
• Don't stand at the mirror for ages looking for flaws.

Sometimes even relatives who mean well talk about weight or looks. These comments can hurt. You can calmly say: I don't want to talk about that. If it really upsets you, tell an adult you trust.

You don't have to love every part of your body. Treating it with respect is enough, and that means looking after it with food, sleep and movement.
