(I wrote the poem in "half rhyme " to let the reader feel the frustrating chaos that was in my head when I wrote this. I hid a few types of "true rhymes' to show the light at the end of the tunnel though.)

Even though I acted light heartedly, my feelings were no commodity.
Because of the cruelty of life, I thought I was collateral damage.
I must now contrive a way to shed this emotional baggage.
To save my mental health, I must rid myself of this encumbrance.
Mistakenly, she took me for a fool and underestimated my competence.
For my friends who care, I had to embellish upon the state of my sustenance.
Wisely, they speculate about the false mask and unnatural deference.
As the rage boils inside of me I must refrain from censuring her for her hypocrisy.
A scar on my heart and psyche, because of this, remain with me indefinitely.
In my mind procures a plan to forget about her existence.
Even with this plan I still want an explanation or recompense.
For now I must just let my nerves cool, let my thoughts fade and let my emotions die.
With this simple list I can probably get by.
