Los Angeles - Chris Brown considered suicide after assaulting Rihanna.
In a chilling trailer for Chris' upcoming documentary Welcome to My Life, 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 fucking monster.
"I was thinking about suicide and everything else. I wasn't sleeping, I wasn't eating. I just was getting high."
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.
