The young royals released 10 films today as part of their Heads Together campaign to change the national conversation on mental health.
The videos feature celebrities and members of the public talking about the breakthrough conversation that helped them come to terms with their mental health problems.
The former England cricket captain Andrew Flintoff and former Prime Minister Tony Blair's spin doctor, Alastair Campbell, are among those seen speaking about their experiences of anxiety or depression.
"When you realise that mental health problems affect your friends, neighbors, children and spouses, the walls of judgment and prejudice around these issues begin to fall," they said.
The films can be viewed on the Heads Together website and YouTube page and are promoted on Facebook, Twitter and Google.
