The dark cave

Trapped and alone,
surrounded by a dark light,
a black shadow,
blocking out the sun,
filling all with cold,
freezing to the core,
the fiery stars shine their last,
the moons gentle glow begins to fade,
all blocked by the shadow of my mind,
the shadow that separates me from the world,
isolates me in this dark cave,
where i can see the passers by,
all living their lives,
can see them,
yet cannot be one of them,
so close,
i can almost touch them,
but an invisible field separates us,
invisible chains hold me back,
heavy as lead,
they weigh me down,
locked tight,
with a lost key,
fiery chains that burn deep within,
hold me here,
in this dark cave,
the black shadow my only friend,
the blade my only companion,
trapped here,
alone, separated from all,
unable to find the key.
