It’s a tough time to be a teenager. Figures show that in 2017, nearly 13 per cent of five- to 19-year-olds had at least one mental disorder. Even more disturbing are the numbers of children self-harming, with hospital admissions doubling over the past six years. These alarming statistics are just the tip of the iceberg. New research shows that depression in 14-year-olds has risen from nine to 15 per cent over ten years. This is often kept hidden, even from parents.
