"Trapped" and feeling like a "monster" is how one young person has described their struggle with mental health.
They were just one of more than 50,000 children and young people who turned to Childline last year because of a serious mental health problem.
New data from the NSPCC shows one in six Childline counselling sessions is now about serious mental health issues.
Those aged 12 to 15 made up a third of sessions, with girls almost seven times more likely to seek help than boys.
