I can get that way as well..(sensitive to sounds and others,actually being really receptive of others around me) it's most likely because of just being tense and an over awareness of my surroundings.But in general,I am an extremely introverted and reclusive person.I don't like get togethers and I don't like to talk to many people,I think I sub-conciously do alot of things to make people uncomfortable and irate just to keep them away from me..I am not depressed (not more so then the average person,though I am bipolar prone lol) nor crazy (not more so then the average person lol) I just like being alone and my solitude.If I was a bazzillionare tommorow,I would buy my parents a house,buy my own house in the middle of nowhere,gate it and security monitor it and live as a reclusive for the rest of my life while living a quiet existence...after traveling the world of course.
