I Am A Thought That Never Sleeps

I am a thought that never sleeps 
I am the image in a recurring dream 
I am emotional torpor manifest 
I am the idea with which I’m obsessed 
I am the drug that they employ 
that rewires my brain so I feel joy 
I am the criminal whose time has donned 
Serving his sentence of lexicon 
I am the politician who suffers slander 
A wordsmith with no anvil and a heavy hammer
