There is a voice in my head

It tells me to run
But I don't
It tells me to grab the knife
But I don't
It tells me to scream
But I don't

It listens to every word, analyzing it
It picks up everyone's emotions and feels it
It sees everything from a car passing by to a leaf in the wind
It feels the tick of a clock from across the street

This is what voices do
They sense things
Everyone has a voice, but their voices don't like to talk
Mine does

I'm not crazy,  I'm just too sain
I see the same as ten others put together would
I feel others emotions and analyze them like twenty therapists put together could
I don't feel it though, the voice in my head does
And he's been screaming at me for the past four years

I could make it stop
But he's the only company I have
