dull knife!
Stab right through and justify
People are using the same insults to injure you, and it doesn't hurt because you know it isn't true and you don't care what they think anymore, you only believe what you say about yourself, nobody else. But you still are taking a blade to your skin, not knowing what to think anymore. It's just the same old thing you do everyday, go to school, get bullied, go home, cut and cry, that's all this lyric is saying, that you just keep following the same routine everyday.
