hellooo..i have the same problem also. only that i am genuinely shy. but yes i do agree with the above that its good to be in the world even tho not of the world. to make an impact in the world u haf to make frens and then show them Who lives in u, rite?
ask God to give u wisdom and see things thru His way. ultimately in the end its ur choice also. He gives u free will to decide.
