Having missed Wales' four World Cup 2014 qualifiers in the autumn the former Liverpool striker is back in the squad for the friendly with Austria on Wednesday night.
And ahead of the clash in Swansea the 33-year-old reiterated his commitment to his country as he prepares to win his 71st cap.
"I've always tried to stay quiet about my future but I'm a firm believer that you don't retire," he told Wales Online.
"I'm fit and enjoying my football and the added bonus for me is that my next game is representing my country - the biggest honour in the game.
"I don't know when I'm going to finish but as long as I feel fit and can offer something to the national team then I will carry on playing.
"It's a drug, that's why I'm here. This is my national team."
Bellamy was also quick to reassure Cardiff fans who worry a midweek run-out may harm his chances of being ready for Huddersfield on Saturday.
"I proved that I can play that much in such a short space of time, it's good for my football to have those periods playing games in succession," he said.
"The fans have seen me play over Christmas in a run of games thinking, 'Can he play this game, can he play that?"'
