Our thoughts and feelings can feel huge and sometimes no matter how hard we try we need a bit of help to make sense of things.
It can feel scary sharing what's going on inside your head with someone else, but it can also be really useful. Choose someone you trust and try and pick a time they aren't too busy.
They may not have any answers or know how to help but sometimes just saying things out loud or writing them down can make us feel better.
Here are some tips from young people on what they found helpful:
Five tips on sharing
Work out what you want to say so you have it clear in your head. I used some little notes to remind me.
Think about what it is you want from them and tell them - it is helpful if they know what it is you need from them (even if it is just to listen). When I spoke to my teacher I asked who she would tell and what she would say so we agreed something I was happy with. It felt a bit like I had some control over it then.
Don't get put off if they ask you to talk another time or don't react the way you want them to. I called Samaritans and Childline and they were really good as people who don't know you to just listen.
I can't do those conversations so I always have to text my Mum.
Things don't always work out the way you want but holding it in your head isn't good, it messes you up.
