It's All In My Head...

Sometimes I feel so alone that I lay in bed unable to sleep because the loneliness consumes me. I have started to listen to my ipod while I fall asleep, because it's easier to listen to music then my thoughts. Why must the idea of being alone scare me so much? I know I'm never really alone, but the unclear future worries me and sometimes I wish I had the confidence to just break out of my shell and not let my fears get to me...
