I need to find the root of my problem.

well i've been sitting here thinking.
I've been trying to arrive at why i am socially inept, how it began, and what am i missing out on
while many of my peers are out at a football game, i am at home posting on message boards and thinking in solitude
and another thing- why must I care to be so perfect?
i get so incredibly angry if im not the best at something
like today
i knocked someone out in rage
and I'm angry just sitting here
JUST LOOKING AT THINGS MAKE ME ANGRY. I am pessimistic and negative. Why must I be better than virtually everyone and virtually everything? I am better than my peers, yet I still feel bad for some reason to stay home like this.
What is happening?
