Returning to London to attend Prince Philip’s funeral last month meant revisiting a city where he felt caged and stalked by cameras once more. It would be a test of his capacity to deal with the anxiety that was resurfacing.

Prince Harry was “afraid” to come to the UK for his grandpa Prince Philip’s funeral in April, fearing it might resurrect old traumas.

“I was worried, I was afraid,” the 36-year-old prince told the Associated Press on Friday while introducing his new mental health show, “The Me You Can’t See,” on Apple TV+.

On April 9, Prince Philip died at the age of 99.

Harry stated that he was able to overcome his fear by employing coping strategies learnt in therapy.

Harry explains in the show that he initially saw a therapist four years ago at the suggestion of then-girlfriend Meghan. They’d had a disagreement, and she saw his rage was misdirected.

Harry, who said in the series’ Thursday debut that he experienced panic attacks and binge-drank when his mother, Princess Diana, died, depended on coping strategies learnt in treatment to get through Philip’s memorial ceremony.

“Going through the motions and being able to lean on the toolbox, and lean on the learnings that I’ve grown from over the past, it definitely made it a lot easier, but the heart still pounds,” he added.

In addition, Prince Harry explained why Meghan Markle did not act on her suicide thoughts in the docu-series. She was frightened of hurting him, he said.

“The thing that stopped her from seeing it through was how unfair it would be on me after everything that had happened to my mum and to now be put in a position of losing another woman in my life, with a baby inside of her, our baby,” Prince Harry explained.

In the episode, Harry discusses horrific childhood memories, such as the day he was photographed alongside his brother, father, uncle, and grandpa walking behind Diana’s coffin during her burial.

“For me the thing I remember the most was the sound of the horses’ hooves going along the Mall,” the 36-year-old told his series co-host Oprah Winfrey.

“It was like I was outside of my body and just walking along doing what was expected of me. (I was) showing one tenth of the emotion that everybody else was showing: This was my mum – you never even met her.”

The series premieres a day after it was revealed that a formal inquiry indicated that a BBC journalist used deception to secure his explosive 1995 interview with Princess Diana. Diana notably informed reporter Martin Bashir about adultery in her marriage and her issues with mental health during the interview. After the findings of the independent inquiry were made public, the BBC apologized.

Harry, who participated in an EDMR (eye movement desensitization and reprocessing) treatment in the series, also mentioned how he struggled with disturbing sensations after returning to London.

“For most of my life, whenever I fly back into the UK, whenever I fly back into London, I always felt worried, concerned, a little bit tense and uptight,” Harry said, saying that the city has been a “trigger” for him since losing his mother.

The series follows Meghan and Harry’s candid chat with Oprah Winfrey, in which they discussed their lifestyle after standing down as senior Royals, mental health, their baby Archie, and much more.
