I'm emotionally intense myself, but am okay with most social situations (I don't love small talk with people with whom I have nothing in common). I don't generally feel like I am on the wrong planet, although I have been known to accidentally come off as aloof or slightly odd.

Please forgive me if I'm completely out of line, but could it be at all possible that you might have Asperger's? Your post did make me think of the name of this forum:
