Suarez is being sent for sessions with sports psychiatrist Dr Steve Peters, the same man who O'Sullivan credits for getting his life back on track.
O'Sullivan told the Daily Star: "I understand what Suarez did, I totally get it. It's like me walking out against Stephen Hendry.
"It's a moment of madness and you think, 'Wow, what have I done?'
"You regret it afterwards but at that moment you're overrun by these emotions.
"Sometimes things like that could have been avoided if you had dealt with them earlier.
"Maybe if I could have diffused what was going through my head I wouldn't have got to that point where I shook Hendry's hand and gave up."
