Johnny football wants a second chance at an NFL career.
And he believes he's discovered one of the major obstacles previously standing in his way.
On Monday, in a taped interview with "Good Morning America," the Heisman Trophy winning quarterback said that he had been diagnosed with bipolar disorder. Manziel revealed that he was diagnosed about a year ago and he is taking medication for the condition.
He also said that he used alcohol as a form of self-medication to combat depression, and that he has since quit drinking.
Never miss a local story.
"You are left staring at the ceiling by yourself and in that depression and back in that dark hole of sitting in a room by yourself, super depressed, thinking about all the mistakes you made in your life," he said. "What did that get me? Where did that get me except out of the NFL? Where did that get me? Disgraced."
Manziel won the 2012 Heisman Trophy at Texas A&M, becoming the first freshman to take home the award. He was eventually drafted in the first round of the 2014 NFL Draft by the Cleveland Browns.
But after numerous off-the-field incidents, including a domestic violence charge by his ex-girlfriend, he managed to stay in the league for just two seasons.
Now, Manziel is hoping for a chance at redemption.
"I don't know what kind of comeback it will be," he said, "but I know I want to get back on a football field to what brought me so much joy in my life and it makes me happy doing as my job."
