The factsheet is designed for young people, their families and friends, to increase awareness of depression, help recognise the signs, and provide guidance on what to do next. It emphasises that it is for general information only and not a substitute for professional advice. The document explains that depression is more than just having a bad day-it involves persistent changes in mood, thought, behaviour and physical functioning, typically lasting more than two weeks, and affecting daily-life activities. It notes that there is no single cause; rather, a mix of factors (life events, biological, psychological, social) may contribute.
