Evil Twin Poem by Glen Martin Fitch

Two bullies, brothers,
ugly, friends to none,
identical
but not in every way
confront me often.
I hear what they say
and I've determined
who's the toxic one.
I dread the first
because he's in my mind.
Whenever I do wrong
I sense him near.  
Though harsh
he preaches
what I ought to hear.
By showing me
my sins
he's almost kind.
Far worse
the other brother
jabs my heart.
My secret self's assaulted
by each slur.
Infected mortally
without a cure,
believing I am bad,
I fall apart.  
For Guilt speaks truth
that hurts yet makes me wise,
but Shame,
his brother,
always speaks in lies.
