Yes she would have. I can’t understand how someone with all her blessings could allow herself to be so unhappy. Jackie O. had her husband’s brains blown out in front of her, but didn’t write a big book about it and use it as an excuse to live a self destructive life.
I think her motto was “Don’t complain, don’t explain.” I don’t remember her ever doing a story about her life and how she felt about things.
Diana was all about how she “felt” about things. That’s what drove the Royals crazy. I don’t think they put much value on feelings or whether they’re happy or not.
