TThe Duke of Sussex said he was “worried” and “scared” to return to the UK for the funeral of his grandfather, Prince Philip.
Prince Philip died at the age of 99 on April 9.
“I was worried about it, I was scared,” Harry told The Associated Press upon returning to the UK.
However, he said he was able to overcome his fear using the coping skills learned in therapy.
“It really made things a lot easier, but the heart is still beating,” Harry said.
It comes as the first three episodes of the series, “The Me You Can’t See”, have been released.
On the show, Harry discusses traumatic memories of his childhood, including the time he was photographed with his brother, father, uncle and grandfather walking behind Diana’s coffin during her funeral.
“For me, what I remember the most is the sound of the hooves of the horses running along the mall,” the 36-year-old told his series co-host Oprah Winfrey.
“It felt like I was outside of my body and just walking around doing what was expected of me. (I was) showing a tenth of the emotion everyone was showing: she was my mom – you never even met her.
The series focuses on mental health, with Harry telling Winfrey that the trauma of the loss caused him anxiety and severe panic attacks between the ages of 28 and 32.
