Former Kansas City Chiefs running back Jamaal Charles has made a heartbreaking admission regarding his post-playing career.

Once one of the league's premier running backs in his prime, Charles revealed that he has battled mental health issues since retiring from the game in 2019.

"People don't really know. I went to try to work with people and invest with people. It didn't go well. I started to lose money and investment. So, I started to get really depressive like suicide... suicidal," the 37-year-old shared on the NFL's "Second Acts Podcast."

Charles spent most of his career with the Chiefs from 2008 to 2016 before concluding his NFL tenure with the Denver Broncos in 2017 and the Jacksonville Jaguars in 2018.

The Texas native earned over $41.7 million in NFL salary throughout his career, excluding endorsements, according to Spotrac.

Jamaal Charles admits what helped him through tough times

Despite facing difficulties, Charles opened up about what helped him overcome the tough times in his post-NFL life.

"At that time I did get therapy, so it's nothing wrong. I did talk to a therapist to talk about suicide thoughts, talk about the hard times. At that time, I still was going through therapy and I still is today," the former Texas player said.

Charles was named a First Team All-Pro in 2010 and 2013 and a Second Team All-Pro recognition in 2012. Additionally, he received Pro Bowl honors four times, in 2010 and from 2012 to 2014.
