Life..as i know it

I don't even think anyone will be reading this so what the hey? I don't know about anyone else but life is... well, unfigureoutable. I can't figure it out. Like what the hell am I suppose to do in life? I'm pretty sure its not to go to school be infatuated, get hooked up and get dumped. That's so meaningless. So what am I suppose to do with my life? I don't want to sound like a whiny teen, but seriously? I don't get it. Why is it the people we love leave us? Why are we killing each other? Why are we unhappy? Why aren't we all happy?:/
