Im Changing. Is this normal, Maybe a Mental disorder?

I've always grown up among women... emotional women. But growing up as a girl, i've always been able to see the reality, in their episodes. I'd like to pride myself in not freaking out or getting emotional about things. The problem is, i really dont get passionate about anything... except for about an hour, and im ready to move on. Lately, i've been finding myself very self-conscience, and thinking about other peoples perspective on things, i wonder what other people around me are thinking, why their doing the things they do, and just watch things more.Im not sure if this is confusing or not. My mind just seemed to have became extremely sensitive, while im in a burn out with all my emotions. I havent been able to really feel in quite a few weeks. Is this normal, or am i just a freak?
