I've seen some pretty insensitive - borderline offensive (well, blatantly offensive) posts on Facebook regarding Chris Cornell's death, and some of it is pretty sickening! The point is that, none of us know what is going on in the minds of those we don't know - happiness doesn't matter, income doesn't matter - a perfect example of this is the film directed by Paddy Considine called Tyrannosaur - those we meet in our every day lives may be dealing with far greater issues than many can comprehend - we've seen many celebrities fall fall foul of this demon, including the likes of Robin Williams, Kurt Cobain, Amy Winehouse, Ian Curtis, etc etc,
With regards to mental health, those of us that have no point of reference cannot comprehend what others are going through. Some of us may be in the same situation at some point in our lives. Just think how frustrating that would be for you to try and convey your feelings to loved ones.
You sort of accept this sort of thing if it was The Rolling Stones or The Beatles, but not bands who were around in the 90s.
