But she wasn't sectioned, she attended voluntarily a private clinic. No shame in that but it's not quite the same as mental hospital.she has spent time in hospital due to her mental health issues so I think she’s genuine.
I agree a lot of celebrities seem to have mental health issues, and seem almost over represented in that regard. But I think part of that is related to the types of personalities the fame game attracts ans also, they’re incredibly rich - they are more able to speak out about their issues, take time off when they need it, than the average person.
