Prince William has confessed he "took a lot home without realising" when he worked as an air ambulance pilot.
The 36-year-old royal worked for the East Anglian Air Ambulance as a first responder for two years and admits it was tough seeing such "despair and sadness".
Speaking at a mental health event in Bristol, he said: "I took a lot home without realising it. You see so many sad things every day that you think life is like that.
"You're always dealing with despair and sadness and injury. The attrition builds up and you never really have the opportunity to offload anything if you're not careful."
Meanwhile, William - who has Prince George, five, Princess Charlotte, three, and Prince Louis, four months, with his wife Duchess Catherine - announced in January 2017 that he would be stepping down from the job and said it was a "huge privilege" to work with the East Anglia Air Ambulance.
