Nine Inch Nails

Am I
Am I still tough enough?
Feels like i’m wearing down, down, down, down, down
Is my visciousness
Losing ground, ground, ground, ground ground?
Am I taking too much
Did I cross a line, line, 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
