Who am I?

Who am I?
I am a person who stands by you
Through thick and thin
Who knows you better than anyone?
But I but I am not almighty!
I am your biggest critic
But yet you don’t fear me
I am your best friend
But you don’t hear me
I wish you open your eyes
And see
How the world truly treats you and
How you treat me
Who am I you may ask
And I say oh! You know me
You face me every day
In the mirror as you stare
I am you
Your reflection
Your soul
Who wants you to be better
Than anyone else in this world
