Counterfeit or Companion

I heard you say it  
You make me feel lonely  
I thought that I fit
Your one and the only
Standing by your side
As though carved from your bone
But when my thoughts slide  
You say you're standing alone
What about all the big love deeds
Or all the constant things
Are you swallowed by the weeds
Away from what my heart brings
Is it that you still don't know  
Why I seem unreliable  
Sparking doubts even though  
To you I am pliable  
Am I caught in hysteria  
Who programmed the thought
In my prefrontal area
But because I forgot
I should be remembering  
It hurts us so much
I feel like a guilty thing
So when put to the task  
I'm looking up to God
Am I companion  
Or just a lonely fraud?
