You're "The Brilliant Dance" by Dashboard Confessional. Lucky; you're the DC songs with some of the best lyrics. Unfortunatly, this means you broke up with someone or got rejected by someone who meant a lot to you, and no matter how hard you try, you just can't get them out of your mind. Good luck, kiddo.
Which of My Fav. Sappy (but good) Emo Songs are YOU?
