so I fight

Darkness threatens to overwhelm me,
So I fight.
it seems I'm punching the air, yet I feel my hands and they hurt
I look at them,
my knuckles are bleeding.
I can feel my heart beating in it's cage
painfully, troubled, tears flow up,
I look around and it's pitch black.
I cry out a prayer,
Silence echoes, my ears ring,
I see a glimpse of light, it's small at first,
but it grows, it illuminates,
So I fight (keep fighting).
