The Duke of Cambridge has said he felt "pain like no other pain" after the death of his mother, Princess Diana.Prince William made the disclosure in a BBC TV documentary about mental health.
He said the "British stiff upper lip thing" had its place when times were hard, but people also needed "to relax a little bit and be able to talk about our emotions because we're not robots".
William also spoke of how working as an air ambulance pilot left him feeling that death was "just around the door".
He said dealing with the loss of his mother - who died in a 1997 car crash - meant he felt he could relate to others who had suffered a bereavement.
He said: "I've thought about this a lot, and I'm trying to understand why I feel like I do, but I think when you are bereaved at a very young age, any time really, but particularly at a young age, I can resonate closely to that, you feel pain like no other pain.
"I felt that with a few jobs that I did, there were particular personal resonations with the families that I was dealing with," he said.He described how the emotional aspect of being an East Anglian Air Ambulance pilot was "difficult", especially having come from the military where feelings tend to be put to one side.
