Britain’s Prince Harry fell into depression when he ​took a break from royal duties in 2019 before he formally stepped down, he told a videocast about grief, where he also discussed feeling “emotionally numb” after his mother died.

Harry, the ⁠younger son of King Charles III, has been open about his mental health struggles and how the sudden death of his mother Princess Diana in a car crash when he was 12 has affected his life.

“I’d spent so ⁠long emotionally numb to a large ​extent because ⁠nobody told me joy was still allowed,” he said on a Masterclass videocast called “Redefining Grief: Building Resilience Through Loss”.

He ⁠also recalled the stressful period in 2019 when tension with the rest ​of ⁠the royal family was ‌mounting, and he and his wife Meghan went to Canada for a six-week break to consider their future.

“Being in Canada, away from ‌the stressful environment where presumably my body was ‌just pumped full of adrenaline, within two or three days, I experienced this adrenaline crash, something that I’d never experienced before,” he said, according to media reports.

“It was ⁠as if I needed stress in order to get the adrenaline to make my brain function because I became useless around the house.

“I actually slipped into depression for about two weeks and I felt like I couldn’t function without adrenaline.”

Weeks after their break in Canada, Harry and Meghan returned to Britain where it was announced ‌that they would stop being working members of the royal ​family.

Two months ago, the couple moved back to Britain ‌with their son Prince Archie, 7, ⁠and daughter Princess Lilibet, 5, after six years living in ⁠California.

Campaigning to raise awareness of mental health issues is one thing Harry still shares ‌with his brother, heir-to-the-throne ​Prince William. The pair are ‌barely on speaking terms since Harry ​repeatedly publicly criticized his family in interviews and his memoir.
