Just jumping in here, I joined the forum to discuss "Diana in Search of Herself: Portrait of a Troubled Princess". I consider it the authoritative book on Diana.
I do agree with the author's suggestion that Diana probably suffered from Borderline Personality Disorder.
I find the Panorama interview, where she questions Charles' fitness to be king, absolutely abhorrent; as well as the other disparaging statements Diana made about him, being that she had children with him.
She wanted out, but she didn't want to be blamed.
We Americans do not understand the monarchy and the fact that it is, basically, a life of duty and service. You will find very few pro-Charles supporters in the US, because of Diana's statements about him, most of which are appalling and not even truthful.
