The video - which had been watched over 500,000 times within hours of its release - is part of the Heads Together campaign, a mental health charity championed by William, his wife Kate and brother, Prince Harry. "You feel like something's wrong with you". In my life, I go, 'Oh, my goodness, look at all these attractive, wonderful things that I have, ' and I should be so happy, but you can't help it if in the morning when you wake up, you are so exhausted.
Lady Gaga started the Born This Way Foundation, which she wrote an open letter speaking of her Post Traumatic Stress Disorder from being assaulted.
"In my life I go, "oh my goodness, look at all these attractive, wonderful things that I have, I should be so happy", but you can't help it if in the morning when you wake up you are so exhausted, you are so sad, you are so full of anxiety and the shakes that you can barely think". The two agreed to do more to eliminate the stigma surrounding mental health issues. You are so sad.
"It's time that everyone speaks up and really feels very normal about mental health", William said.
Speaking from Kensington Palace to Lady Gaga at her home in Hollywood, William told the singer numerous issues he had seen from his work with veterans, homelessness and addiction charities stemmed from mental health issues. "But it was like saying 'this is a part of me, and that's okay'". "It's the same as physical health".
With many of his latest charitable efforts centred on ending the stigma around mental health, Prince Harry reveals that his late mother Princess Diana would be especially proud.
Harry, filled with anxiety and anger, acknowledged that he went through two years of "total chaos" in his 20s.
After handing out registration packs to runners which included their official number, timing chip and a Heads Together headband, he said: "I've shared, just as much as everybody else has during this campaign".
"I still have shock within me - 20 years later".
