We need to rethink the conversation around mental health - psychologist Lucy Foulkes explores how and why. How do mental health problems arise? How do we distinguish between the 'normal' challenges of modern life and actual illness? Is society really experiencing a new mental health crisis? In this urgently needed book, psychologist Lucy Foulkes investigates what we know about mental illness - and shines a light on what we don't. It offers a profound new approach to how we think, talk and help when it comes to mental health.
