Resentment simmers beneath my skin,
Alive and nipping.
My thoughts demands my constant attention,
Harsh and unwavering.
I'm bitter and the memories won't leave,
Forceful and reminders.
Sometimes they slip away out of my mind,
Waiting and ready.
Resentment simmers in a cauldron of emotions,
Powerful and hostile.

Let it soak with the others, but don't let it overpower them. Understand it, feel it, and then control it.
