Of not being the person you want to be. And of having the wrong perspective, but you can't seem to think of it in a different way, and you're stuck with this miserable feeling. Then you try to run away from reality by distracting yourself, but everything else you do, you're distracted by the very thing you're running away from. But what is it you're really running away from? "Nah, it's nothing..It's not worth talking about", because you're afraid of being judged, and eventually (hopefully), it'll come to pass.
But how will it come to pass, if you don't confront it?
