Do you spend too much time online? Can't concentrate in class or is your sleep disturbed by your time on social media? Have a conversation with someone you feel comfortable with and trust, like a good friend, your parents, sister or brother. This can bring relief and help you sort things out. You can also find help together.
If you don’t immediately have the courage to tell someone in your direct surroundings, then try to approach someone who is familiar with similar experiences, such as a GP or a student counsellor at your college or university.
