It was telling that she said 'as I keep saying to H it isn't enough to just survive..'
I felt that was possibly as the advice she has been given by PR people, Harry, and maybe any other Royals (but maybe not as she doesn't seem well supported), is "ignore it, hold your head high, get through it, and eventually people will forget about it. You'll survive it." Which is basically what the RF (apart from Diana) do about all bad publicity.
I felt that the "my friends told me not to marry Harry" thing was really sad. I can understand why she mentioned it, but to him it must have felt like the sort of thing yelled in a row "all my friends warned me not to marry you!!" ie this was a mistake and now I am seeing that my friends are right.
Harry probably promised at the time that she mustn't worry, he would look after her & defend her from the press, but of course there is only so much he can do against the might of the tabloids, and now he is worried he will lose her and panicking.
I actually feel really sad after seeing it, and I wish I hadn't seen the interviews. I deliberately didn't watch the programme but then all the pertinent bits were on the news.
