Trapped in a Mental Prison

There are many types of pain we can feel.
There's physical, that will mend over time;
mental, that's unlikely ever to heal-
either can turn at the drop of a dime.
Among others, these two stand out the most.
Abandoning senses, clouding recall,
making comfort fade away like a ghost
and down into your own darkness, you fall.

Mental injury can change many things-
you are the puppet, pain pulling the strings.
Your whole life is always just out of reach,
hitting barriers you can't seem to breach.
You yell and scream, but you'll never be free.
All of your actions are lost to the sea.
