Possibly got it from his mother. Prince Harry was probably able to manage it but his wife is his enabler. In that case, therapy isn't helpful. Life goes on. Can't always be a victim.
there are many shocking things in his book but one that stands out to me (besides thinking of his mother while he put Elizabeth Arden cream on his todger)...was this one about killing his dad

So far it hasnt been explained if he is trying to claim it was an actual fighter jet or if he was just cosplaying on a video game. Either way, it is disturbing.
