"The Dog Whisperer" Cesar Millan recently opened up about his struggle with depression after his divorce.

In 2010, Millan hit what he calls "rock bottom" after the death of his favorite dog and the end of his marriage to wife Ilusion Millan -- even attempting suicide by overdosing on pills.

Millan, who has two sons with his ex-wife, told The Tampa Bay Times this week that his divorce and attempted suicide helped him to re-focus on the important things in life.

"You hear this sentence, 'What doesn't kill you makes you stronger,'" he said. "That became real for me. It made me closer to people."

Millan also said he hopes his experience will help his loved ones avoid similar low points.

"I'm happy I went to rock bottom and now I know the symptoms," Millan said. "As a father I want to see the signs before my kid or anyone around me in my life has any kind of depression, sadness ... My faith got stronger."
