Sorry guys, was out for the day. Diana told those stories herself, she dictated them into a tape recorder for Andrew Morton and they're on public record. She was giving them as an example of how "desperate" she was, but truth be told, it sounds like everyone else around her must have been equally desperate.
Yes, she was sent to two psychiatrists in turn. She didn't like either and stopped going to both. She hadn't wanted to go to a psychiatrist in the first place. She didn't think she needed them and seemed bullish about them. Her grandmother gave her valium to take, but she refused to take them.
I don't know if either of those psychiatrists got a chance to get to know her well enough to diagnose her. There's nothing in the public arena, except a lot of armchair diagnoses based on her own tapes. Usually its personality disorder that rises to the top. We will probably never know.
