Kevin Kuranyi has apologised for walking out on the Germany squad during their World Cup qualifier against Russia on Saturday night.
The Schalke striker left the Westfalenstadion at half-time of their 2-1 World Cup qualifying victory over Guus Hiddink's men in an act of petulance after being left out of the 18-man matchday squad.
Germany coach Joachim Low was quick to condemn the Brazil-born 26-year-old, announcing on Sunday that Kuranyi would not play for the national team again while he was in charge.
Kuranyi, who has scored 19 goals in 52 international appearances, tried to explain the reasons for his walk-out at a press conference on Monday.
"It was wrong to leave so early and I have apologised for that," he said. "I always felt happy with the national team. I have never had a personal problem with a coach - not at club level nor at international level.
"I have always tried to understand people and that is the way I am naturally. But I have left them in the lurch."
After suffering taunts from Schalke fans during a difficult start to the season, everything appeared to erupt inside Kuranyi at the weekend at the home of his club side's bitter rivals Borussia Dortmund.
"As a Schalke player, sitting in the stand in Dortmund is hard enough," he added. "Nobody knows what is going on inside my body, in my mind and how bad it all is.
"The Germany coach has accepted my apology and he knows full well why I reacted like I did and understands me. It all just got too much for me."
With Kuranyi's international future now on hold - at least while Low remains in charge - he was quick to re-evaluate his targets over the coming years.
"I still have enough goals I would like to achieve," he said. "But my future hinges on what other people decide. The people who really know me know I am not the kind of person who just does the thing I did on Saturday night.
"You have got to understand I have always tried to do everything for everybody as a player, whether for club or country."
Kuranyi also explained being left out of the World Cup squad in 2006 had left a scar.
"We had a World Cup in our own country and Kevin Kuranyi was not there," he said. "Unfortunately, I was not there for my biggest dream of playing in a World Cup.
"To miss a World Cup and then fight your way back takes a lot out of you. The situation was tough. I told the Germany coach how I have been feeling for the last three years. Not even my father can understand what I have done."
Kuranyi was back in training for the Royal Blues on Monday morning.
He said: "Whoever knows me knows that I will always try to fight back again. I will do everything to be successful with my club Schalke.
"It is a tough time for me and I just hope this passes quickly and that people relax. From tomorrow, I will try and train and work as normal again. I want to thank everybody who has believed in me and everybody who stands by me. I have felt a huge amount of support."
