Prince William has recently opened up about how becoming a father brought back painful memories from his own mother's passing in his youth.
William was just fifteen when his mother, Diana, Princess of Wales tragically died in a car crash in Paris, 1997.
He has made the revelation for a very important BBC documentary on mental health.
"Having children is the biggest life-changing moment, it really is," he told the interviewer.
"I think when you've been through something traumatic in life - and that is, like you say, your dad not being around, my mother dying when I was younger - your emotions come back in leaps and bounds because it's a very different phase of life."
"And there's noone there to, kind of, help you, and I definitely found it very, at times, overwhelming."
The dad of three praised his wife Catherine, saying that her support had been vital to the pair evolving as parents.
"Me and Catherine, particularly, we support each other and we go through those moments together," he said.
"Emotionally, things come out of the blue that you don't really expect and that you've never really dealt with.
"It's one of the most amazing moments of life, but it's also one of the scariest."
The new documentary, titled 'Football, Prince William and our Mental Health,' is expected to air in the UK on May 28 on BBC One.
