Ties that bind

My mind is in chains,
The language is keeping me from saying
What my body can't do quite well
Because of the ties that hold me
Flesh and bones, blood like stones,
Hopeless screams and groanes...

I'm my own prison cell!
I'm in the walls, the floor, the ceiling, 
I'm the words that are still echoing,
I'm the windows that always let the light go,
I'm the door and I lost the key a long time ago,
I'm my own prison cell and the prisoner's me...
