Mental health problems are very common and are experienced by three children in every classroom (www.youngminds.org.uk). People can and do recover. It's easier to make a full and quick recovery if you get support or treatment early, so it's important to let people know if you're experiencing difficulty coping with your thoughts or feelings.
Talk to your parent, or carer, your teacher, youth worker, school health advisor, doctor, college welfare worker, or someone else you trust. It's important to let an adult know how you're feeling as it's the first step to getting the help or support you need.
