Johnny Manziel said in an interview with Good Morning America that he was self-medicating with alcohol to fight depression.

The Heisman Trophy winner and former NFL quarterback, who is CFL property of the Hamilton Tiger-Cats, gave his first interview since beginning his comeback attempt, and opened up about his troubled past.

And according to a report from ESPN that had more quotes from the interview, Manziel said he was diagnosed as bipolar a year ago and is taking medication for the condition. 

The interview will be broadcast in full later Monday, but Good Morning America gave a teaser on Twitter.

“I was self-medicating with alcohol," Manziel said. "That’s what I thought was making me happy, helping me get out that desperation to the point of where I felt that I had some sense of happiness."

"But at the end of the day, when you wake up the next day after a night like that, or after going on a trip like that, and you wake up the next day and that’s all gone and that liquid courage and that sense of liquid euphoria that’s over you is all gone and you’re left staring at the ceiling by yourself and you’re back in that depression and back in that hole, that dark hole of sitting in a room by yourself being super depressed, thinking about all the mistakes you’ve made in your life. What did that get me? What did that get me except out of the NFL? Where did that get me, disgraced?”

More details to follow.
