Chalk it up to the pressure of fame.
Or possibly to a pre-existing mental condition.
Or maybe a combination of both.
But the following celebrities each suffered legitimate mental breakdowns at some point in their careers.
Were you aware that all these stars carried so much personal barrage at times?
1. Mischa Barton
The former OC star sadly ends up on this list twice. She claimed she was suicidal and was placed in 5150 psychiatric hold against her will back in 2009. She then exhibited off behavior in the backyard of her West Hollywood apartment and agreed with police in 2017 that she needed to seek help from a doctor.
2. Kanye West
His ranting went from funny to frightening in late 2016 when he allegedly attacked an employee at the gym and then willingly spent nine days in a hospital, receiving assistance.
3. Britney Spears
The most famous of them all, right? After so many years in the spotlight at a young age, Britney snapped in 2009, culiminating in the shaving of her own head. She was also placed in a 5150 hold.
4. Marilyn Monroe
During the 1960 filming of The Misfits, which would become her last completed movie, Monroe was admitted to the Westside Hospital in Los Angeles for a nervous breakdown. She later died of a drug overdose.
5. Demi Lovato
Lovato checked herself into a treatment facility in the fall of 2010, later telling Seventeen magazine that she had a nervous breakdown and realized she needed help after her manager and parents pulled her aside for an intervention. She has been very open since about her eating disorder and former drug use.
6. Mariah Carey
Following the bombing of her film Glitter at the box office, Carey was taken to a hospital July of 2001 in Westchester County, New York and then moved to another hospital in Connecticut. She was released in late August.
