How Bobby Brown Finally Got Clean and Sober

The singer had a long struggle with drugs and alcohol until 2013.

"I didn’t want my kids to grow up and see me in that type of light," he said. "I've always been one to want to grow to want to be better and better on the next day -- if I'm bad yesterday, I want to be better the next day, especially for my children. I mean, my children mean everything to me, everything. I wouldn’t be here if it wasn’t for them. So I try to be as strong as possible for them every day. And it takes every day for me to do that."

"I’m doing great. Of course, on an everyday basis, I still think about her and I still go through it," he said. "But, I think I'm a lot more comfortable with knowing that she's in a better place, knowing that she's not in pain anymore, you know, and I'm just grateful for that."

In June, Brown acknowledged to ABC’s Robin Roberts that he and his ex-wife had failed their daughter.

"We should have been better," Brown said in the interview for a special edition of “20/20.” "We could have been better."
