+Nine Inch Nails -- Hurt
+
+I hurt myself today
+To see if I still feel
+I focused on the pain
+The only thing that real
+A needle tears a hole
+The old familiar sting
+Try to kill it all away
+But I remember everything.
+
+What have I become
+My sweetest friend
+Everyone I know
+Goes away
+In the end
