I am great fan of jesus christ, but still i feel i am an atheist, wot 2do?

Jesus exists as a historical figure-- a mortal teacher, if not the son of God. The lessons you're referencing have nothing to do with theism or atheism, but with simple human kindness and courtesy. It's not really necessary to ask "wot 2do?" You believe in these lessons-- patience, kindness, love, forgiveness-- and you're an atheist. Nothing wrong with that.
