I dislike socializing with other people. Do I have a disorder?

I prefer to keep things to myself and only speak with others if necessary. I don't have any friends nor do I see any practical use for them. I am an straight A's student and going to be attending a top school in Septembre. My guidance councilor suggested to my parents that I see a psychiatrist, simply because they think I am not normal and have deduced that I may be a threat to society in the near future. What are your thoughts?
