The film, which is part of the #OKtoSay series run by Heads Together, captures a conversation between Their Royal Highnesses that occurred at Kensington Palace as they looked ahead to the London Marathon 2017 and reflected on the growth of the campaign over the last year. The conversation covers a range of topics including the emotional changes new parents go through, bereavement, the stresses of modern childhood, and dealing with trauma in the workplace. The Duke and Duchess and Prince Harry are incredibly grateful to everyone who has shared their stories in recent weeks. And having asked others to start conversations on mental health with their friends and families, they wanted to show that they are taking part as well. They hope the film shows how positive a conversation on mental health can be. The Duke and Duchess of Cambridge and Prince Harry began the Heads Together campaign to end stigma around mental health. Heads Together aims to change the national conversation on mental health and wellbeing, and is a partnership with inspiring charities with decades of experience in tackling stigma, raising awareness, and providing vital help for people with mental health challenges.
