True, it is not easy to know the truth. But then I would not say "what she thinks what she endured", but I would say "if what we hear is the real truth".
I did not know anything. Just yesterday I researched this topic first time.
I came across an interview with her father and clearly he has problems respecting her borders and some trust issues towards her, so I can imagine that Meghan got some issues out of this. And her stepsister seems quite an ordeal to me. So, her family is far from clean as far as I have seen. If she got some emotional traumas out of this, then probably the truth will be somewhere in the middle. I do remember that she has been welcomed with open arms in UK when they got married.
So, obviously, people with a few brains could have figured out at that time, that there would appear little babies with a tinge of different skin color (but nobody seemed to worry about that at all), which makes her story about racism a bit weird IMO. But I am not a clairvoyant. And also it seems to me that Harry agreed with her story. But then I also read that some believe Meghan is a narcissist, which would mean that she totally could have played Harry (that's what narcs do), who seemed to be smitten by her.
In short: This seems quite a messy situation we have here. But soon we will know more, I think. Such secrets usually don't stay hidden long.
