Underachiever?

I feel as if I have lost my luster, become dull. These past few days have been all a blur to me. It's as if my perception of the world has been narrowed down to just eat, sleep, school. I can't really seem to function as I used to or even perceive and engage in daily activities, normally. My confidence level has also been dwindling, I know it makes sound materialistic, but I only feel good when I look good. That's why I am in desperate need of shopping. It has also dawned on me that a lot of people who I consider my friends aren't really acting 'friend' like. I feel abandoned and withdrawn, as if on the eve of teenage depression. It's silly but I do think that I am becoming depressed... Or is it just another defense mechanism for myself--- Another way to run and hide? Flight over fight? Whatever the case, I need to get my act together and raise my grades; which are exceptionally drab.
