Bellamy is enjoying some of his best form in years at Eastlands.
But he told Sky Sports: "I know there aren't four or five years ahead of me with the injuries that I've had.
"Maybe I've got one or two years at the most and it'll be all over before I know it, so I'm just enjoying it."
Towards the end of a career packed with controversy and unfulfilled potential, Bellamy feels he is close to showing the world what he can do.
"The last few months have given me a huge sense of pride. I think people have seen what I am as a player now," he said.
"I have always got goals in my career, but am I a one-goal-in- two-games player? No, I'm not, but my career has been one-in- three, which is not too bad."
