Lyrics of I have no mouth but i must scream

My brain hurts i'm suffering from a pure overload i need some time to get away before my thoughts take over me i need some time to reminisce with a vacant mind, so tension free help me find away to; cure myself, i'm falling off the edge; disarm myself, i'm falling off the edge; shout out loud, i'm falling off the edge; hold on tight, i'm falling off the edge oh please no, this isn't the way i wanted it i can feel my veins pulsating in my head the walls are slowly caving in, dilapidated in a sense, slipping in and out of this state of disrepair the fix comes knocking at my door and i am not around missed opportunity to cry its like i have no mouth and i must scream in time to cure myself... i'm falling off the edge
