Renfro, a sophomore, didn't participate in the Huskies' spring camp for what coach Chris Peterson called "personal issues." Renfro said in a lengthy statement on Twitter that he was receiving treatment at a hospital during that time "in a special program for people like me, that taught me how to cope with my problems and what to do when I hit my lowest of lows."
Renfro, who also said he would no longer attend the university as a student, thanked doctors and his close friends for helping him to get "out of a dark place before it was too late."
"Waking up in the morning got harder and harder, till it got to the point where I didn't want to wake up at all," he wrote, describing his life before he decided to get treatment.
Renfro, who caught 13 passes for 178 yards in his only season for the Huskies, said he now has a better outlook on life.
"This isn't the end of me, just the end of a certain chapter. I will conquer this, and not let this situation conquer me. I'm on a journey to find my happiness again," he wrote.
