Prince Harry has described the "scary" moment he thought he might lose his memories of his mum during therapy.
The Duke of Sussex made the revelations during a live stream event about trauma and healing with author Dr Gabor Maté.
Harry described how finding a therapist and "unpacking" the death of his mother, Princess Diana, was a "huge weight" off his chest.
But the prospect initially scared him, as he became worried that he would lose "the feeling that he had of his mum" in the process.
“My awareness of myself was distorted by my environment but also society," he said.
“When I found my therapist and started to unpack 12-year-old Harry at the point my mother died, that started to unravel all sorts of other moments. It was scary."
He added: “One of the things I was most scared about was losing the feeling that I had of my mum.
" I thought that if I went to therapy it would cure me, and that I'd lose whatever I had left, whatever I had, I had managed to hold onto of my mother."
But the Duke said therapy had in fact helped him move forwards.
“It turns out that wasn’t the case,” he told Dr Mate.
“I didn’t lose that. It was the opposite.
“I turned what I thought was supposed to be sadness - to try to prove to her that I missed her - into realising that actually she, she really just wanted me to be happy. That was a huge weight off my chest."
The revelations came during a live video event to promote his memoir, Spare.
During the Q&A, he told Dr Gabor Maté: "I certainly don’t see myself as a victim", adding that he wanted to help others by "sharing my story".
The Duke also said: "And I have never looked for sympathy in this, for me.
"It's for me experiences that I've had throughout my childhood, throughout my life, throughout my 38 years, albeit relatively short. I'm not looking forward to becoming 40, that's for sure."
Harry also said he wished he had begun counselling sooner, and felt like he "learnt a new language" once he started going regularly.
