It may be hard to know what to do as they may not want to talk about it.
Here are some tips:
Let them know you've noticed something's wrong.
Encourage them to talk. If they don't want to, wait and find a quiet time later on.
- Tell them about the helplines they can call.
But if you're really worried, don't try and sort it out yourself.
Talk to an adult you can trust or call one of the helplines.
