"I was on top of the world and I ruined it," she shared at the time, noting that she spent years battling her addiction, as well as a devastating bout with postpartum depression. "I'd think I hit rock bottom, but then there's that trap door that opens."

"This hasn't been easy and there were a lot of ups and downs," she added of her journey to sobriety and happiness. "But I don't regret even the ugliest things that have happened to me. I feel incredibly accomplished. And I feel like I have a second chance."
