Absolutely Nothing

I spend way too much time doing absolutely nothing. Sometimes I forget the meaning of time. All time is are seconds, minutes, hours, days, weeks... months... years... They just blend together in one giant magnificent blur of miserable joy. Completely filled with me doing nothing important. Thinking too loud, and speaking too soft. My mind just flows with music, art, emotions and ideas. But that is all they are. They exist but never truly become what they should be. Emotions wasted, Ideas never put into action, songs never sang, art never to be drawn. I wish I could knock some sense into myself, so that one day I could actually make something of this life I was given. All I know is writing. I write everything, for that is the easiest outlet for my thoughts. I wish I knew how to express everything in a simpler fashion, so that everybody could hear me. I wish a lot, but why shouldn't I? I'm not satisfied with the way I am now, So all I can really do is wish, dream, and think. I can't sleep, I barely eat, I haven't talked to my girlfriend in a month because she is grounded, my family drives me insane everyday, my headaches are getting worse, it feels like the entire universe still thinks of me as a loud, obnoxious, ADD asshole without issues, and I am not okay with any of it. But i have no idea how to change any of that.... How are you supposed to change something you can't even comprehend yourself?
