Chris Brown considered suicide after assaulting Rihanna.
Chris Brown
The 'Yeah 3x' hitmaker admitted he felt "like a monster" after he attacked his then-girlfriend in February 2009.
Speaking about going from "America's Sweetheart to public enemy number one," he said: "I felt like a f***ing monster.
"I was thinking about suicide and everything else. I wasn't sleeping, I wasn't eating. I just was getting high."
And the 26-year-old star's mother, Joyce Hawkins, admitted the incident marked the "worst day" of her life.
In a trailer for Chris' upcoming documentary 'Welcome to My Life', she said: "That was the worst day of my life and probably his life.
"I felt like I was going to lose my child."
Despite the way his reputation plummeted after the assault - for which he was sentenced to five years of probation, one year of domestic violence counseling, and six months of community service - and subsequent other legal problems, the 'Beautiful People' singer insists he will never be "finished".
As the trailer draws to a close, he said: "If there was ever a doubt in your mind that Chris Brown was done, he was finished? I wouldn't bet on it."
A release date has yet to be set for the documentary, which features contributions from the likes of Jamie Foxx, Usher, Jennifer Lopez and Mary J. Blige.
