About 20 per cent of the world's children and adolescents have mental health disorders or problems, and half of them develop before age 15. Despite that, stigma and limited information and resources often keep mental health in the shadows until crisis strikes. Monday at 1930GMT, young people from around the world share their experiences with mental illness, and explain why they think prevention is better than cure.
