Eating me away

It's eating me away I said to God It's rotting in my mind It's like a cancer Is there anything, anything at all to numb the nothingness I need a reason to breathe It's eating me away Yeah, yeah.... It's eating me away It nibbles at my brain The question of my existence And the matter of pain I shake my fist, I shake my fist At the cosmos and my insignificance I need a reason to breathe It's eating me away
