LEGENDARY singer Mariah Carey revealed she only slept two hours in almost a week before she had to go to a mental health facility.
The record-breaking star, 50, has opened up about her struggles with bipolar which will also feature in her new autobiography, The Meaning of Mariah Carey.
Mariah said she goes to some "very dark places" in the book, some of which she's never even told to her closest friends.
"There's a lot of stuff that I'm dealing with in the book that I have never dealt with, even in conversation with some of my closest, closest friends," she Jane Pauley on Sunday Morning.
She then made the shocking revelation that in 2001 when she turned her hand to acting in the feature film Glitter, the backlash against the film lead almost destroyed her life.
The emotional toll was so great she barely slept.
Mariah explained: "The Glitter era, it was an intense time."
"There's very few people who understand, like, being under the constant scrutiny of the world, or the press."
She added: "I couldn't even say the word 'glitter.'"
"It'd be, like, people around me, we had to say 'sparkle' instead of 'glitter'!"
Then Mariah revealed she had checked into a rehab clinic and was there during the September 11 terrorist attacks on New York and Washington DC.
She knew she had to go to rehab when she had only got two hours sleep in six days.
"That's not acceptable," Mariah proclaimed.
"But I allowed myself to be put in a position for that to happen. I was working so hard and I wasn't about to let everything I'd worked so hard for just to slip away. So, I worked myself into the ground."
"I was in a very dark place that ended up almost completely destroying my life.
"But when the towers were collapsing, I left that place, and somehow survived, like we all had to.
"I had my own personal drama attached to it, 'cause that was the day that 'Glitter' [the album] was supposed to be released."
She described the rehab clinic as "a place that I didn't belong, a facility."
The Fantasy singer first opened up about her bipolar diagnosis in 2018. Bipolar disorder is a mental health condition that causes extreme mood swings.
“Until recently I lived in denial and isolation and in constant fear someone would expose me,” she told People at the time.
“It was too heavy a burden to carry and I simply couldn’t do that anymore. I sought and received treatment, I put positive people around me and I got back to doing what I love — writing songs and making music.”
Mariah has bipolar II disorder, which means she will have periods of depression as well as hypomania, including irritability, sleeplessness and hyperactivity.
“I’m actually taking medication that seems to be pretty good. It’s not making me feel too tired or sluggish or anything like that. Finding the proper balance is what is most important,” she said in 2018.
“For a long time I thought I had a severe sleep disorder.
“But it wasn’t normal insomnia and I wasn’t lying awake counting sheep. I was working and working and working … I was irritable and in constant fear of letting people down.
"It turns out that I was experiencing a form of mania. Eventually I would just hit a wall. I guess my depressive episodes were characterized by having very low energy. I would feel so lonely and sad — even guilty that I wasn’t doing what I needed to be doing for my career."
Mariah's tell all book also talks about her troubled relationship with her mom Patricia and her siblings.
Mariah and her mom have reportedly had a troubled relationship for years, and one major fallout was in July 2001 when Patricia called the police while her daughter was allegedly struggling with mental health problems.
The insider adds: “Yes, Mariah was having a breakdown and was later diagnosed with bipolar disorder.
"The whole cop thing was just Pat’s jealous, mean-spirited nature. Mariah was at no time a danger to herself or anyone else.
"Patricia wanted the world to know her vulnerable daughter was breaking down, she enjoyed Mariah being brought down a peg or three. I would have never forgiven her, it was a nasty, vindictive thing to do."
They went on: "She’s always been jealous of Mariah, she was once an opera singer herself and a voice coach for many years, and ended her career when she had kids.
In recent years, the family has been devastated by internal feuds with Mariah’s eldest sister Allison, 59 - a recovering drug addict and currently homeless - filing a lawsuit last month against her mother saying she forced her to have sex with strangers at the age of ten and watched other kids being abused in a satanic cult.
Mariah doesn’t speak to Allison or elder brother Morgan, 60, who lives off-grid in Hawaii.
Four years ago, Allison was attacked in her home by an intruder with a baseball bat and had to have brain surgery, but neither Mariah or Patricia visited, with Morgan branding Mariah an 'evil witch' for abandoning their sister.
In a recent interview with Vulture, Mariah, 50, discussed her relationship with her estranged siblings, who she now refers to as her "ex-sister" and "ex-brother" - branding them "heartless".
She said: "Here’s the thing: They have been ruthlessly just heartless in terms of dealing with me as a human being for most of my life. I never would have spoken about my family at all had they not done it first.”
Mariah also spoke about her mother during the interview, and how she has included her in her book to some extent.
"I tried to make her feel like I really do think she did the best she could," she told the outlet.
