How about a first hand explanation?
In the 1970's I had the misfortune of being treated like a "star' whilst doing shows for a big company and making "big" money... I was busy as hell, popular, and thought I was "somebody" (though I wasn't)... but I was also a kid that was being raised by two oppressive right-wing extremists who viewed Billy Graham, Anita Bryant and Richard Nixon as being right as well as righteous and expected me to fit that mold... two people that lived in extreme denial, hiding behind closed doors and closed curtains, thinking the outside world would never know their "truth"
But I was coming into my latter teens and early adult years, disco was big and cocaine even bigger... an "accepted" factor in the show biz sense of reality. Couple that delusion with the perpetual party life of the Gay scene in those days (well, into the 80's AFTER AIDs hit the fan) and voila! It's easy to get lost and become a chronic junkie before age 20 and going back and forth on the rehab wheel before it finally stuck... that was almost 28 years ago. But the ride doesn't end there; especially for a "has been" that "never was"... you constantly beat yourself up for your failure both, vocationally as well as by way of how others see you... most especially your parents... at 51 years in age I still have deep fears over my 76 year old, frail & senile father because of how he brutalized us "in the day"...
... you see, there's always a back-story...
Entertainers exist in a make-believe world and when you get that sudden boon of carnal success it goes to your head... very few can handle it! That is why you have so many "one hit bands" or those that only crank out the first 3-5 albums for their recording label (not to be confused with today's way of doing things... people can poop out CD's faster than most people change their socks and without any established entity standing behind them)... truth be know, that is what most major record companies like A&M only sign on for those first 3-5 records, they know when the ego-driven burn typically takes its toll and of course, if you're still functioning at the end of that 5th album them put you on a hell tour in the hope of burning you out... that way you can't easily bounce back and cut them out of your next decade or three making "real" money vs. the petty cash they allow you to have initially.
Are you seeing the other ingredient yet? Having to kiss but and take table scraps from the corporate entities that "make you"?
I've seen it happen in Music, Magic and the Comedy world all of them environments that are more than conducive to "being" an alcoholic and/or addict. Though I will say that things are changing for the better in that world because of a higher degree of health consciousness by the performers as well as their sense of global obligation... neither has been witnessed at before, and at such an amazing level of commitment.
So that's the gist of it all... I've helped mega stars get to the recovery facilities more than a few times, one of which just died this past year. Show Biz as a whole, is a cruel mistress for most, no matter how famous or wealthy you become through it. Even after you've actually "made it" the odds of surviving beyond a single decade and retaining longevity in the industry, are stacked waaay against you; and having a "normal" life is essentially unheard of.
Oh! One Last Thing... it is the one vocation one seems to have no choice in taking on. It's a part of who you are, which is why you take the abuse and deal with the depression, heartaches, anxiety, and everything else. Thankfully most folks are smart enough to avoid it.
