Luke Chadwick hit the heights when he won the Premier League with Manchester United, but off the pitch he was plagued by anxiety and depression.
As a young player, he suffered abuse and bullying over his appearance that sometimes left him reluctant to leave the house.
"As a 19-, 20-year-old it should have been the best time of my life but for a period of time… I didn't want to go to the shops, I didn't want to go out with my friends… I would just want to stay at home because I was so scared that people would talk about the way that I looked," he says.
