"Kurt Cobain. Formed Nirvana in '87, and went from playing record store gigs and dive bars in the late 80's to putting out Nevermind, a record that knocked Michael Jackson out of the #1 spot in Jan of '92. Back then, something like that was unheard of and considered impossible in the industry. For the next couple of years Nirvana were arguably one of the biggest and most popular rock bands in the world, but Cobain was already thinking of ways to essentially sabotage the bands popularity because he was so uncomfortable with how famous they got while dealing with his own inner demons and drug addiction. They performed at the Reading Festival in '92 in what many consider one of the great live rock performances of all time. Put out their second major studio album, In Utero in Feb of '93, that went to #1 instantly despite the record company originally thinking it was 'unreleasable' and some major retailers refusing to sell it due to the album art and the song 'Rape Me'. Performed their iconic MTV Unplugged set in November of '93, despite Cobain being in the heavy throes of herion addiction and them not knowing if he'd be able to perform until showtime. In March of '94 he intentionally OD'd in Rome while on a European Tour. Came back home, went to rehab for a couple of days, hopped the fence, and week later he blew his head off with a shotgun. Nirvana has sold over 75 million records worldwide despite only being a band for less than 7 years, and only releasing essentially 2 major label albums (Nevermind & In Utero), 1 indie album (Bleach), 1 album of b sides (Incesticide), the MTV Unplugged album and a 'greatest hits' album (Nirvana). I'd say that qualifies as a pretty destructive downward spiral, especially considering their ascent was so rapid as well." - DrRDuke

"I would have to say Whitney Houston. I suspect many people here were either not alive or too young to remember how insanely big Houston was. She was literally the biggest female artist in the world and one the biggest artists, and this was before social media. She holds the record for having 7 consecutive number-one singles on the Billboard Top 100, record sales of over 200 million, a host of awards including 28 Guinness World Records. The only other artist that could stand shoulder to shoulder with Whitney in regards to success would be Michael Jackson. However between 2000 - 2005 her entire career and life completely disintegrated. Her marriage to Bobby Brown, her addiction to crack, the car crash that was her own reality TV show utterly destroyed her career. She attempted a comeback in 2009/10 by doing a world tour but it was painful to watch to say the least. She was unable to hit high notes, she no longer had the range she had, many performances were cancelled, I think it was one in Australia which was an utter car crash. She made the audience wait for hours and when she did appear she simply couldn't sing. Pretty much everyone booed her and she gtfo in a very short time. The general consensus was her tour was a major flop. She tried to comeback a couple times afterwards but she never got even close to her former glory. I have never seen somebody who arguably was the world biggest artist fall so hard and fast as Whitney Houston." - GhostRiders

"The Hollywood of yesteryear had more than its fair share of career implosions such as Fatty Arbuckle and Harry Langdon but few can match Wallace Reid. Described as "the screen's most perfect lover", he was an all-round athlete and musician who wanted to move from theatre to film. He approached Vitagraph Studios with a story hoping he could direct it but the studio jumped on the opportunity to cast the 6 foot blue-eyed Reid as a matinee idol. By 1922, he had appeared in nearly 200 pictures and even tried out for the Indy 500. Reid was hiding a secret however. In 1919, he had been involved in a train wreck and was prescribed morphine for his injuries. As the pressure of stardom grew, he rapidly became addicted regularly spending 1,000 dollars on morphine but audiences noticed his rapid weight loss and gaunt features. He collapsed on set in October 1922 and was sent to a sanatorium where he was locked in a padded cell as he tried to detox. He died of influenza on January 19th 1923 and his death was a huge shock to the public, the first celebrity drug death."

"gia carangi. she started modelling in 1978 at age 18 . reached her peak in 1979 and was considered THE supermodel. but by 1980 her career was already in steep decline due to her hardcore drug addiction alongside her erratic personality making her a difficultly to work with. by 1981 her career was basically over at only age 21 . she tried to make multiple comebacks but it never stuck and officially left the modelling industry for good in 1983. she ended up working as a store clerk and even a prostitute for some time but in 1986 she ended up dying of AIDS at age 26 suspected to be caused by contaminated heroin needles. she was in such poor condition when she died then when the doctors picked her up the skin fell off her back. no one in the fashion industry attended her funeral or even knew she had died. she fell just as quickly as she rose. in the end no one she thought cared about her in new york ended up being there for her during her final months except for the friends she made in rehab. though through the demise of gia brought about the rise of cindy crawford. cindy and gia share a lot of resemblance so many photographers would use her in place of gia because she was far easier to work with. she was even nicknamed “baby gia” at the beginning of her career." - AltruisticBreak9

"I know it’s a bit of a niche but… Conor McGregor. He wasn’t everyone’s superstar. Ask people from Ireland and they’ll tell you they hate his guts. Still, while he was a controversial and cantankerous figure, he was mostly inoffensive on his meteoric rise. Blew through contenders like paper, destroyed the greatest featherweight ever with one punch, and his ego got out of control. He got brought back down to earth by Nate Diaz, adjusted his approach, and went up a division to dethrone the lightweight champ. First simultaneous double champion. Conormania was IN. Everyone was raving about him. Highest selling PPV star in MMA, celebrity appearances… if you thought of combat sports from 2015 to 2017, you thought of the name Conor McGregor. All that box office success drove him to a matchup with Floyd Mayweather. Months of back and forth trash talk as Conor was known for but as the talk progressed it felt like Conor was losing a step. It seemed like all the wit and charm he had on the rise was eroding. Then came the fight, and it was the usual spectacle of a Conor performance, but Floyd destroyed his aura of being untouchable. At the same time Conor got exactly what he always dreamed of: more money than any human should have. This money led to a sense of invincibility. He flew halfway around the world to throw a dolly at the bus of his rival Khabib with a pack of Irish gangsters. The glass from the window the dolly smashed injured several fighters in that bus. He was arrested, but got off easy. Money. The Khabib fight was the biggest in his career. Two years of layoff, returning to face an unstoppable juggernaut. The press conferences were packed with vitriol and pure bile rather than the typical tongue in cheek charm. It was uncharacteristic - or rather, it was the mask coming off at last. He got humiliated badly, and everything went wild. Cocaine. Sexual assault scandals, whether true or not. Alcohol. He started his own whiskey brand. Apparently it’s garbage, but don’t take it from me. Take it from the old man he sucker punched in a bar for refusing to drink it. Another two years off - he comes back against Donald Cerrone, someone well below his level and everyone knows it. He’s surprisingly mild mannered and kind in the lead up to the fight. It’s unclear if this is the new him, the real him, or another mask. He seems to be back on track. Another year off. Thanks, covid. He makes a cordial fight offer to former opponent Dustin Poirier, world class good-guy of the sport. The lead up to their rematch is mild and gentlemanly as befitting a seemingly reformed McGregor and a laid-back Louisiana slugger. It’s an electrifying rematch regardless - and the last time we ever see this side of him again. He gets humiliated again. Badly. In the aftermath, he’s cordial, but in the lead up to the rubber match something snaps. Cocaine. Anxiety. Alcohol. SOMETHING goes wrong and goes wrong badly because he returns with an uncharacteristic, substanceless viciousness. He starts involving Dustin’s family in dirty, charmless ways. Attacks him at the press conference. He can’t get his charm going because it’s been replaced with coke and cash. The fight itself ends with McGregor on the ground, his leg snapped in two, screaming obscenities at Dustin and promising that he and his family will die in their sleep. He uses his post fight interview to rant about how it’s not over and he’ll still batter Dustin in the parking lot (on one leg). There’s nothing left of the young Irish kid who made it big. Now there’s just a bitter laughingstock ranting on the floor about another man’s wife and leaving the sport that made him famous behind on a stretcher." - DrJonesPHD62

"I think of Chris Farley. His SNL career started in 92(?), his real break came with Tommy Boy in '94. Dead by '98 at 33 years old. Horribly addicted to drugs, alcohol, food, and other impulse related stuff probably. Probably gained 100lbs in his 6 year run. OD'd on a "speedball" (as everyone seems to) Everybody of that era claims he was the funniest guy they've ever known, and most of em talk about being frustrated both by his lack of any self worth (despite how beloved he was), and a feeling of "inevitability" about his early demise. Obviously Chris wasn't destructive like some of the other scumbags mentioned on this thing. He was simply self destructive. People like to compare him to John Belushi. They had pretty much the same self destructive trajectories, both fat dudes, both highly energetic performers. But as people I think they were very different. I think he's more comparable to Robin Williams. They both had this like insatiable need to make people laugh, and they both had this super-human energy. By all accounts Chris, like Robin, was an incredibly sweet and sensitive person in private life. Apparently hed spend a lot of time volunteering at children's hospitals in Madison Wisconsin, and he didn't even talk about it. I've heard a million takes on Farley, and it's always heartbreaking (and telling that 25 years later, people still talk about it and can't get over it)." - conradbirdiebird
