Prince Harry: 'It's been unbelievably tough for us' to separate from royal life

"I'm just really relieved and happy to be sitting here talking to you with my wife by my side, because I can't begin to imagine what it must have been like for [my mother] going through this process by herself all those years ago," Harry said, "because it's been unbelievably tough for the two of us. But at least we have each other."
