Suarez admits he was "in denial" after biting incident.
The Barca star saw psychologists and initially thought he would retire from football.
Luis Suarez says the strong negative reaction he got from the biting incident with Italy's Giorgio Chiellini made him think of retiring.
The Barcelona star was banned for four months after he bit the Italy defender on the shoulder in Uruguay’s World Cup clash back in 2014, the third time he bit an opponent on the pitch, after similar incidents at Ajax and Liverpool.
Speaking to Fox Sports, via the Mail , Suarez said: "My wife asked me what happened and I told her we simply collided. I did not accept the reality, I was in denial, and that was a big mistake."
Suarez revealed he sought professional help.
'I turned to psychologists and that really helped me to accept my mistakes and grow,' he said. 'I suffered a great deal during that period, for my wife, my children and my team-mates.
'I was treated inhumanely, though. I had signed for Barcelona and they didn't even give me a presentation to the media. I thought my career was over and I'd have to retire.'
