She flew the Atlantic when she was several weeks further into a geriatric pregnancy than she is now, and for a fucking shopping trip, gift grab and bar hopping activity. Like shit she isn't flying because of pregnancy.
We all know she isn't flying because she's not welcome, likely explicitly or implicitly not invited anyway, and is too much of a coward to face them all if she were invited. Let alone the British public. Or Piers Morgan.
And nobody believes she was denied mental help for suicidal ideation unless they're wilfully ignorant at this point. There's again zero evidence for any of her claims, and an awful lot to refute it, including the RF's history of allowing members as far back as Princess Margaret to get inpatient mental help, both Harry and William having mental health counselling for years, and Harry himself being part of a mental health charity. Hell, even Philip's own Mother Princess Alice had a known spell in a mental institution after the war.
I personally believe that the truth is that she wanted to do a paid promotional deal to check into her mate's newly opened posh person wellness 'retreat' (that she mentioned on her instagram previously) for a spell during her pregnancy and THAT is specifically what was denied, because merching and financial backscratching while a working royal is not allowed, and this was spun into 'denied permission to go somewhere' with the lie about her mental health added to add outrage to what otherwise would be a total non-story or rather a story about her own lack of financial ethics, lack of understanding of her role and of course, her own personal greed.
