Hi Mr. Stranger. *You sound very intelligent and level headed and insightful about yourself. I applaud you. *It sounds like you are or were concerned about not being the social norm, for not having an interest or desire to be social? *I have to say, I think you are fine, and also, just the fact that you are concerned, to me, is showing high intelligence and other positive traits that not everyone has. *It sounds like you wish you were interested in others, because you have to be social in your life somehow. *I hear two things in your post. *At first, "what's wrong with me?" and next, empowerment about who you are. *Go with the latter empowerment, which I think you are! *I'm now interested in the selfishness theory / point of view you've got going. *I see validity in it, but i havent thought much about it and it does sound rather like one side of a two sided coin, or, one side in a complex issue. *I want to check out that website Lost in the woods gave. *If you are wondering about a diagnosis, let me know. I personally think the DSM is flawed. *But can be helpful. *
