Nine Inch Nails - Discipline lyrics

Am I still tough enough? Feels like I'm wearing down Is my visciousness Losing ground? Am I taking too much? Did I cross a line? I need my role in this Very clearly defined I need your discipline I need your help I need your discipline You know once I start I cannot help myself And now it's starting up Feels like I'm losing touch Nothing matters to me Nothing matters as much I see you left a mark Up and down my skin I don't know where I end And where you begin I need your discipline I need your help I need your discipline You know once I start I cannot help myself Once I start I cannot stop myself
