There is NOT END PORTAL

The world i have is infinite, and i have over 1 year playing in this world, when i finally desided to fight the dragon, i tried to get to the portal location and i finded out that there was NOT end portal, i copied the world and played in creative mode, but guess what, i was correct, there was NOT portal, i also tried to find another portal, but it was the same thing, the eyes just got stucked in a space of the air, without some portal arround.... What i can do? I want to keep this world.
