What emotional state am I in?

I am not here to whine or complain about my problems, because I do not feel that I have any at the moment. I am simply hoping that someone will understand my state of mind. I used to be emotional about things, I was very vulnerable and had a strong conscience. I wanted a bright future and to succeed and excel in life. As I am getting older (I am 17 at the moment) I find myself caring less and less about things in my life e.g. school finding a job etc. My emotions are seeming to harden up and break away from lack of stimulation, however i don't see this as being a bad thing. My former dreams of excellence have been overtaken by the the strong force of just "getting by". I strive to be content and have no aspirations. My "dream in life is to be average. Some may think that this is merely apathy, however I am not apathetic. I care about things, I just don't strive to achieve what I could if I tried. Some may think of this as "laziness", But I am not lazy about the things that I am pionate about, however the only thing I am pionate about is just getting by.
