Unspoken Words

How do I rid myself

of these unspoken words? 

The ones that sit in my head

waiting for their release.

They prod at my thoughts,

planning their escape,

But I've kept them caged in

and I can't let them take shape.

The pain that they hold,

hurts me inside,

but I can't let them leave

the pain will subside.

These words that I hold

have the force of a storm.

I'm almost stronger than them,

but I'm starting to conform.

One day they'll break free

and will take me down too, 

that day will come

and I'm afraid that it's soon.
