And Stokes crossed Black Cats chief Roy Keane last season when he was one of three players to miss the team bus for a Championship game at Barnsley in March.
But he told the Sunday Sun: "I have to be careful that people don't get the wrong impression about me.
"Sometimes I think I get the harsh end of the stick.
"I know there have been a couple of problems but as far as I'm concerned, that's all in the past.
"The bus incident was a big mistake but I spoke to Roy Keane about it, apologised and that has been sorted out."
Stokes added: "As far as the Ireland situation was concerned, I had a niggling injury so I wouldn't have been able to go over there and play anyway.
"It was just a misunderstanding. I spoke to the gaffer about it but I genuinely didn't realise that I had to contact Ireland. They had a different view on that."
