"Being someone who grew up in church and went to Catholic school, I had faith, but I questioned a whole lot of things," she explained. "I questioned God. I needed to understand why would this happen."

As time passed, Latifah found hope.

"I would get these little messages clear as day, as if someone said it to me: 'Don't throw it all away. You're going to get through this,'" Latifah said. "I literally heard that sentence come to me through the haze of alcohol. Now, that wasn't me saying it to me, because I didn't feel that way, but I feel like that was God's way of saying, 'Don't throw it away.'"
