Manziel entered rehab shortly before the Browns released him in 2015, but he continued using alcohol as a free agent in his years-long battle with depression.
Manziel was charged with domestic assault in April of 2016 and the victim, then-girlfriend Colleen Crowley, said in court documents that Manziel struck her so hard that she temporarily lost hearing in one ear and that he threatened to kill her. Manziel faced a year in jail but the domestic assault charge was dismissed last November when he successfully completed requirements of a court agreement that included taking an anger management course and participating in the NFL's substance-abuse program. Manziel also said he has been training and is hoping to return to playing football. Where did that get me except out of the NFL?
"I had a sense of entitlement about what I had accomplished at the age I had accomplished it and I felt for a while I got so ingrained caring only about what Johnny wanted, even when I thought I was doing what I wanted, I was miserable".
"I saw the trickle down effects of what I was doing in my life, that were meaningless and pointless and selfish", he said.
Johnny Manziel says his mental health is now a top priority in going from a Heisman Trophy-winning National Football League bust to a hopeful comeback story. Manziel said. "But I know if I stay on these meds and I continue to do what I am doing right now".
"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". Where did that get me except out of the NFL? I'm doing the little meticulous things I have to do on a daily basis to try to keep this (points to head) right and everything else means the most to me.
He said it's hard "watching other guys do what I want to be doing" while he's "sitting on a couch being a loser". "I can't help my mental makeup or the way that I was created".
He said his goal is to get back into the NFL.
Manziel said his loved ones, including his fiancee, model Bre Tiesi, and his father, who once said his son wouldn't live to see his 24th birthday, "would all agree that they see a drastic change" in his behavior.
