Silence

If I have been silent
it is because my throat has become hoarse
from one
unending scream
rising, rising, 
my breath is gone, 
a kettle on a stove, 
and higher still, 
then fading from earshot
but the scream 
carries on
and I do not know
how long for, 
til the atrocities stop
or til I am finally gone
the scream devours me
and still I scream
or is this scream me?
