Avicii, a well-known DJ, committed suicide in 2018 at the age of 28.
His issues were exposed in a series of unsettling and tragic journal writings written before his demise.
Fans will be able to get insight into his grief when Mans Mosesson's upcoming book, "Tim - The Official Biography of Avicii," publishes his journal entries.
The book, titled Tim Bergling, will be released next month and will look at how the Swedish DJ, whose true name is Tim Bergling, battled with drug misuse issues.
Mans met with Avicii's parents, Klas and Anki Bergling, as well as his friends, family members, ex-partners, and coworkers while putting the book together.
Avicii rocketed to international popularity in 2011 with his song "Levels," but he ceased touring in 2016 due to opioid and alcohol addiction.
The musical talent became addicted to prescription pain medication when he was 22 years old. Excessive drinking and acne medicine resulted in pancreatitis, which was transported to the hospital.
Avicii began writing about his experiences during his time at the medical facility after a doctor encouraged him to stay sober for at least six months.
"I had a hard time accepting never drinking again though strongly suggested from all doctors to wait at least a year before even having a beer," the DJ wrote.
"Of course, I didn't listen to the majority of the doctors. I listened to the couple who said it was ok if I was careful."
He added, "I was ignorant and naive and touring the world, still on the never-ending tour - because once you've circled it once, guess what? You start right back over again."

The "Wake Me Up" singer also said in the journal that he loved his stay at the medical facility, describing those days as "the most anxiety- and stress-free days" he had had in the previous six years.
"Those were my true vacations, as depressing as it might sound," he shared.
"The relief of going from extreme pain to none, knowing that no one is expecting anything other than for you to wait it out (which is the only way of treating pancreatitis) and then recover was huge. It was an extreme relief, considering the insane schedule I had kept up until that point."
