Lyrics

So, here we go I can't let you down, you'll never know That I lied to you from the start Well, here I am Singing my heart out, woah I wish you saw what I see The things you hate inside of me Said you're leaving Now I got to say that I've let go You're on your own Said you're leaving Now I got to say that I've let go You're on your own Said you're leaving Now I got to say that I've let go You're on your own
