:[ I think im going nuts. what to do?

well you must have something to communicate with him like his screen name or phone number, but other than that, be positive. some people go crazy when their bf/gf is on the other side of the world right now. You live in the U.S., your bf lives in Canada, so don't think that 6 months would be torturous for you. Those people, who's bf/gf are far away from the U.S. right now, must be having their worst times of their lives......ever. So be positive....
