To the outside world, Matt Chisholm had it all: a successful career as a TV journalist and host of the popular reality TV programmes Survivor and Celebrity Treasure Island. He had loads of friends, a great sense of humour, a happy marriage and two lovely sons. But behind the broad smile for the camera, Matt Chisholm was depressed, anxious, crippled by perfectionism and imposter syndrome. And he had a problem with the booze. Matt Chisholm has written a candid memoir about his mental health journey, called Imposter.
