The Uruguayan has faced questions regarding his bite in his first Barca press-conference.
Suarez bit Giorgio Chiellini during a group-stage match against Italy at the tournament, and received an instant ban from football for four months.
Although the Uruguayan still continues to try and appeal the ban with his lawyers, he admits he sought help following the incident.
“That is a private matter (the bite), but I am speaking to professionals. The right professionals,” Suarez said at his first press-conference as a Barcelona player.
“I don't like having to go back (and think about it). When it happened afterwards I was really down."
“I spoke to my psychologist, he said I had to face reality and say I was sorry.”
As it stands, Suarez’s first competitive appearance in a Barcelona shirt could be against bitter rivals Real Madrid, with the two scheduled to meet in La Liga on the first day of the striker’s freedom to play.
His first conference also confirmed that a move to the Nou Camp had been long in the making, with technical director Andoni Zubizarreta admitting ‘we've been chasing Luis for two years’.
Suarez also says that his move to the Catalan giants was something he had been dreaming about for a long time.
“For years I've been dreaming of playing for Barca...I didn't think it was something that was ever going to happen.”
The move from Liverpool allows the Uruguayan another fresh start, having become a somewhat controversial character in the Premier League. His talents were never really in doubt, but attitude and integrity is something many fans have called for in his play, with Barcelona now representing an opportunity for him to be the complete player.
