My friends say they're proud of me  For taking our breakup so casually  But they don't see what lies beneath my smile  It appears that I'm okay  And I moved on when you walked away  But the truth is since you said goodbye    [Chorus]    I'm invisibly shaken and quietly breakin'  Desperately takin' one breath at a time  Beneath this composure I know it's over  Baby I'm dying cause you can't be mine  But I will never show the toll it's taking  Cause I'm invisibly shaken    If it looks like I don't care  It's not killing me seeing you here  And hearing you say you want to try us again  Believe me it ain't easy being this cool  But too many times girl I've been your fool  And I know I'd just end up here again    [Chorus]    Invisibly shaken and quietly breakin'  Desperately takin' one breath at a time  Beneath this composure I know it's over  But baby I'm dying cause you can't be mine  But I will never show the toll it's taking  Cause I'm invisibly shaken    Baby I'm dying cause you can't be mine  But I will never show the toll it's taking  Cause I'm invisibly shaken
