During a sit-down with Good Morning America that aired Monday, Manziel said he's taking medication as a result of being diagnosed with Bipolar disorder roughly a year ago.

"I'm working to try and make sure I don't fall back into any type of depression, because I know where that leads me, and I know how slippery of a slope that is for me," Manziel said.

After he was selected in the first round of the 2014 NFL draft by the Cleveland Browns, he only played 15 games during his two-year stint in the league before things went further downhill.

"I had a sense of entitlement at the age I'd accomplished it and I got so ingrained about only caring about what Johnny wanted," Manziel told ABC.

The low point was a domestic violence charge that was eventually dismissed by a Dallas County judge as part of a plea agreement.

"I don't know what kind of comeback it'll be, but I know that I want to get back on a football field and do what brought me so much joy in my life and makes me happy, doing (it) as my job," Manziel told ABC.
