Prince Harry talked about how his grief over losing Princess Diana impacted his life on "Good Morning America" ("GMA").

The Duke of Sussex appeared on "GMA" to promote "The Me You Can't See," the Apple TV+ docuseries he produced and cocreated alongside Oprah Winfrey.

In the interview, Robin Roberts asked Harry about his thoughts on how it felt to grieve Princess Diana when the whole world was grieving with him.

"There were so many people of all ages that need to heal and also for one reason or another are unable to heal or maybe unaware that they need to heal," the duke responded.

"If we hold onto grief, it manifests itself and appears later in life," he added. "That is what I've learned from this process."

In "The Me You Can't See," Harry revealed that he had panic attacks before royal engagements as a result of his mother's death.

The duke went on to say in the "GMA" interview that filming "The Me You Can't See" also made him see how much helping others has aided him in his healing process, particularly after having a conversation with Robin Williams' son Zak.

"The sort of parallel thread between what happened with him at his age and what happened to me at my age, it's remarkably similar," Harry said of himself and Zak.

Harry went on to say that Zak told him "his service to others has helped heal him" in a follow-up conversation after they filmed for the show.

"I think that was a really key moment for Oprah and myself and Zak," he said. "It's been true for me starting the Invictus Games."

Prince Harry founded the Invictus Games in 2014, an annual competition for injured veterans and military personnel.

"To watch other people heal is part of our own healing process," Harry went on to say.

In "The Me You Can't See," Prince Harry also discussed the ways Prince Charles' parenting impacted him.

Harry said Charles would often tell his children, "Well, it was like that for me so it's gonna be like that for you," when things they didn't want to do would happen.

"That doesn't make sense," Harry went on to say. "Just because you suffered, doesn't mean your kids have to suffer."

"In fact, quite the opposite. If you suffered, do everything you can to make sure that whatever negative experiences you had, that you can make it right for your kids," Harry said.

The duke went on to say he thinks parents should "break the cycle" of suffering for their children.

"Isn't this all about breaking the cycle?" he said. "Isn't this all about making sure that history doesn't repeat itself? That whatever cycle of pain and suffering has happened to you that you don't pass on."

"The Me You Can't See" is available for streaming on Apple TV+.
