Johnny Manziel joined Good Morning America Monday morning to discuss his “huge downfall” and his potential comeback.

Manziel’s fall from college superstar to out of the NFL happened very quickly and publicly. He told GMA that he was “self-medicating with alcohol,” and it wasn’t until his mother broke down that he saw the trickle down affect his actions had on others. Manziel also had a simple “no” to the question if he was still drinking.

“I was self-medicating with alcohol,” Manziel said Monday morning. “That’s what I thought would make me happy and get out of that depression,” Manziel said. “When I would wake up the next day after a night like that, going on a trip like that, and you wake up the next day and that is all gone, that liquid courage, or that liquid … sense of euphoria that is over you, is all gone.

“You are left staring at the ceiling by yourself, and in that depression and back in that hole, that dark hole of sitting in a room by yourself, super depressed, thinking about all the mistakes you made in your life,” he added. “What did that get me? Where did that get me except out of the NFL? Where did that get me? Disgraced?”

Manziel also revealed he was diagnosed with bipolar disorder and is taking medication.

“I am taking medication for bipolar, and I am working to try to make sure I don’t fall back into any type of depression, because I know where that leads me and I know how slippery a slope that is for me,” Manziel said.

“At the end of the day, I can’t help that my wires are a little bit differently crossed than yours. I can’t help my mental makeup or the way that I was created.”

With respect to his potential football comeback, Manziel isn’t sure what that will look like, but he knows he ultimately wants to return to the game that brought him so much joy.

“I am coming back from a huge downfall,” Manziel said. “I don’t know what kind of comeback it will be, but I know I want to get back on a football field, to what brought me so much joy in my life.”
