Twenty years later, Harry has revealed the heartbreak he felt on the day of the highly-publicised funeral.
“My mother had just died, and I had to walk a long way behind her coffin, surrounded by thousands of people watching me while millions more did on television,” he said.
“I don’t think any child should be asked to do that, under any circumstances. I don’t think it would happen today.”
Harry also recognised how publicly speaking about his struggles could help others.
“You can tell the signs in people…. in my case, suit and tie and every single time I was in any room with loads of people which is quite often, just pouring with sweat, heart beating bop, bop, bop, bop – literally like a washing machine – just like ‘oh my god get me out of here now. Oh hang on I can’t get out of here – I’ve got to just hide it’,” he said.
“You go through all that stuff and then you meet other lads who’ve had a similar journey … and you can help them and you can have a bit of banter…. Once they realise ‘Hang on I’m not the only person here – There are so many other people who have suffered and recovered – I’m going to go and sort this out and get help’.”
The prince also revealed the heavy burden which comes with the throne, and how, none of the younger members of the Royal Family want to be king or queen.
“People would be amazed by the ordinary life William and I live,” he said. “Even if I was king, I would do my own shopping.”
The prince however, who is currently dating Suits star Meghan Markle , stressed the importance of keeping “the mystery” of the monarchy alive, carrying the legacy built by his grandmother, The Queen.
“Is there any one of the Royal Family who wants to be king or queen?” he asked. “I don’t think so.
“It’s a tricky balancing act. We don’t want to dilute the magic. The British public and the whole world need institutions like it.”
