In his new memoir, Friends, Lovers, and the Big Terrible Thing, which is out on November 1st, the 53-year-old Friends actor describes his battles with drug and alcohol addiction.
He spoke to People magazine about his revelations, including the fact that just four years ago, while he was on life support, doctors gave him a "2% chance to live."
In 2018, Perry, who was 49 at the time, had surgery for what his publicist claimed was a gastrointestinal perforation and spent months in the hospital rehabilitating.
His book, however, describes how he was genuinely fighting for his life after his colon ruptured due to narcotic misuse.
He was on life support and in a coma for two weeks.
He had to use a colostomy bag for nine months and spent a total of five months in the hospital getting better.

"I was placed on a device known as an ECMO machine, which manages your heart and lungs' breathing for you.
