Some interesting points there. The problem really is that mental health is so subjective. Some people function OK in situations where others disintegrate. Also, some people will blame others for their negative feelings when often they would be better looking at themselves, while others will take ownership of their feelings and try to address these. It is clear that Meghan suffered from being in what must be a very restrictive and demanding situation as a Royal, and I don't think many clear-thinking people would criticise her for wanting out of it. I also think that she (along with a whole line of other people in a similar situation) was mistreated by the press. But for me she is looking to blame the Royal family for a status quo that comes with the institution that it is (and that she chose to join) rather than anything actively done by them to abuse her. I may be wrong of course, but noone really knows the truth either way.
