NEW YORK — Tyler native Johnny Manziel is speaking out — revealing he’s been diagnosed with bipolar disorder. And he wants to get back to the NFL. In an interview with “Good Morning America,” the former A&M football standout admits he’s struggled with depression — and turned to drinking and partying as a way of coping. Manziel says he would self-medicate with alcohol, only to wake up to nothing. Manziel says about a year ago he was diagnosed with bipolar disorder and is now on medication for that. He also says he’s stopped drinking. Manziel hasn’t played an NFL game since 2015 but says he’s working on a comeback and is asking NFL owners to give him another chance.
