Sadly, this is why so many celebrities rely on vices to find happiness and far too many go off the rails. Flakes who live in a bubble without even an understanding of how little intrinsic value they bring to society, but once in awhile a hanger on or prescription deliverer tells them how important and insightful their views are.
Part of this really is tragic and one wishes an intervention would have been applied. Whether it's Prince on meds, Sinead O'Connor talking about loneliness and suicide, Katy Perry out to lunch after a terror attack, others succumbing to their demons on a daily basis. It's a waste of life because so many aren't grounded and lack that perspective. Illustrates that one can't find happiness with fame alone, and it's worrisome that so many look up to these people and take their word as gospel. A form of radicalization: the spreading of insanity.
