I got bit by a snake...?

i got bit by a water moccasin and i know there posinous but nothing happend, no swelling, no pain (except the bite, that hurt) or anything?

Either you were lucky (about 40% of all people bitten by venomous snakes are not injected with venom) or you were not bitten by a water moccasin. My guess is you were mistaken as to the snake that bit you. Are your bite marks two neat pinhole punctures or more elongated? The former would indicate a water moccasin, the latter some other type of snake.
