a mere shadow of my former self...

I am only a mere shadow of my former self. I was not this kind of a pessimist back then. I was one of the people that always look at the brighter side of life. But now, I can only show others that side, but not looking at that myself. I always fake a smile to my real friends, just to show them that I am happy, but in reality, I'm far from it. I am always unsatisfied. Always wanting more. The thing that made me into this mess is just 2 years back. During my last year at highschool.
