Who am I?

I often thought
I knew who I was
What it meant to be me
Why I do what I do
But now,
After you,
I'm beyond broken
I'm a blind man in a room full of mirrors
Confused, with no hope
I prided myself,
Well, maybe that was the mistake,
I tried to help
But in the end, you made my heart ache
I'm going through the motions
The key to life is simple:
Give up
Let in
Find a shepherd
Follow
Repeat
The sheep may be ignorant
But they're content eating weeds
Even when luscious pastures are close
They'll follow their shepherd
Forever,
Or
Until
He
Changes
Political
Parties

Obscene
Yet doable
Unwanted
But required
Vast
But unrequited

Maybe it's a bad idea
But this sheep
Has had a taste of real grass
And the more he chews
Reluctantly
On his dandelion
The more he realizes
Slowly
He needs the grass to live
But as he arrives at the pasture
The grass is burnt
The trees are cut
And he turns,
And he weeps
Because he knows what he has lost.
