As he drove home late at night, a voice in Lawrence Prestidge's head told him to press the gas pedal, crash his car and take his own life.

He listened to the command - and the decision to do so changed everything, albeit not in the way that he had originally intended.

The Boy Who Lost His Smile tells the story of how Prestidge came to suffer from mental ill health, and how he battled his demons to improve his state of mind. It wasn't a linear journey, but he hopes that sharing the ups and downs will help others who face the same challenges - and show them that they, too, can come out on the other side.
