"I think I was just overloaded with everything, with carrying six years of so much," said the singer, 26. "I always take a licking and keep on ticking...it just became heavy for me to the point that I just wanted to be away from the noise ... There's so much that people don't understand. They just see the glitz and the glamour, and they feel like life is so perfect, but we're human and we go through things."
The day she attempted suicide, Barrino was threatened with a lawsuit by Paula Cook, the wife of Antwaun Cook, with whom she had been having an affair.
But Barrino -- who just released her new album, Back to Me -- said that's not the reason she tried to take her life.
"I think everybody feels like I tried to harm myself over a man, but you know I've been in a lot of bad relationships," she said. "I think that had somewhat to do with it because it was so heavy, it was brand new information, I was already going through so much. But I think it was just six years of everything, of me holding all that stuff on the inside and not letting it out...I got very, very tired."
When she was hospitalized, "I figured out, 'Oh god, this is going to be more drama,'" she said. "I know all these nurses they know me, they probably voted for me."
But one nurse in particular helped her regain some confidence.
Now working with a life coach, Barrino said, "I'm just going to go back to that young lady I was on the Idol that people fell in love with. I'm back to me."
