James Casling's 15th birthday should have been a day of celebration. Instead, it was the day his father took his own life.
Soon James too began having dark thoughts - attempting suicide on several occasions.
James was sectioned and taken to hospital. One morning he was asked if he wanted to play football and it changed his life.
He now plays for Queen's Park Rangers mental health team.
At Wembley Stadium today the Duke of Cambridge said he wanted to harness the power of football to tackle the rise in suicide particularly among young men by launching his new 'Heads Up' campaign.
James says football allowed him to confront his darkest thoughts and stay alive.
