Knockout - Too Little, Too Late Lyrics

What did I do to make you so sad? I blame this on myself. I sit here complaining meanwhile your feelings changing. You won't talk, I can't sleep. The promise made I didn't keep. Look at the mess that I am in. You can't undo mistakes like this. There's really nothing I can do but try and make this up to you. You're keeping your distance ignoring my existence. I hurt you, you're upset, something that I cannot forget. Maybe I can't help it, can't put an end to it. Sometimes the things we say are only temporary. I can't undo what I've done to you.
