Not the first stanza, and "the" isnt the word, its just the first that came into my head.
My tiredness is turning to annoyance,
and then from that to hatred.
I can no longer wait for you as i pretend behind my new mask.
You have changed,
and it annoys me that you are no loner who you once were - cheerful, happy.
I no longer want to be here...by your side.
That could be edited to something like this (this is only a suggestion btw alex)
"My tiredness, transforming into annoyance, hatred,
I cant wait for you, im pretending behind this new mask.
You have changed, happy cheerful loner no more,
I no longer want to be here,
By your side."
I just think it flows in a less prose stlye and more of a poetic style. But then again its your choice. *shrug*
