Former Texas A&M quarterback Johnny Manziel revealed he has been diagnosed with bipolar disorder Monday in an interview with Good Morning America.

In the interview, the first freshman to win Heisman trophy winner discussed his diagnosis, his short stint in the NFL with the Cleveland Browns and that he was clean from alcohol.

Manziel, who was drafted first overall by the Browns in 2014, hasn’t played football since being released in 2015 and entering rehab.

“I had a sense of entitlement about what I had accomplished at the age I had accomplished it and I got so angry and only caring about what Johnny wanted,” Manziel said. “Even when I thought I was doing what I wanted, I was miserable.”
