This Mortal Coil

I come and stand at every door
but no-one hears my silent breath
I knock and yet remain unseen
for I am dead, for I am dead
I'm only seven although I've died
in Hiroshima long ago
I'm seven now as I was then
when children die they do not grow
my hair was ________, my ________________
my eyes grew dim, my eyes grew blind
death came and turned my bones to dust
