You're a Dagger

Dagger to the heart That's all you are And have always been I'm addicted to you Yet you don't care about me You've only ever cared about her Always have, always will I see you everywhere I can't get you out of my head I thought I was over you I was just numb My heart is on fire There's a dagger in my chest Blood is leaking everywhere I'm in my own hell You're just a dagger in my heart I hope it goes numb again soon Because I can't seem to get over you
