I agree @DuchessOfPort .
It is glaring that Harry can't find anything positive to say about his incredibly privileged life to balance against the parts he found (understandably) intrusive.
Would he have been accepted into Sandhurst (and an elite regiment at that!) if he wasn't the Queen's grandson? How many people are in a position to develop a taste for polo? Or go on long visits to Africa (country always unspecified, which is one of my pet annoyances, as if the whole of Africa is still the playground of wealthy Europeans!)?
Sadly, thousands of children around the world have to deal with the death of a parent (one of DD's friends parents has just died from cancer 😥). All too many have to deal with the financial impact on top of the emotional impact, as they are living in, or on the brink, of real poverty.
Very few have access to any help in dealing with that - but we know Harry has access to therapy, because he has said so himself.
I think having too much money is a curse (although preferable to having nothing) - having to make a living, having to deal with reality, having to get up in the morning when you would rather hide under the duvet, is in many cases helpful. It gives a routine, structure, makes you interact with other people and get out of your comfort zone a little. Avoiding discomfort doesn't help in the long run.
I say that as someone with personal experience. I am not saying 'just get over it'. But that learning to live with trauma is about creating a daily routine that gets you through the crises, bit by bit. There is no magical answer, but there is a lot you can do to help yourself. And I am glad I had enough money for emergencies, but not so much I could insulate myself from the helpful (but uncomfortable) aspects of daily life.
