Tonguetied

I had something to say when I began
But over time it dwindled to no point.
The sentences I started turned and ran
Away from me; my words were out of joint.
I stood there gaping like a dying fish
Strangling in an excess of air;
I couldn't even try to speak my wish,
And truth be told, I didn't even dare.
I simply babbled, and began to speak
Of nothing out of fear of everything.
My tongue kept wagging as my mind grew weak,
And nonsense has, alas, no better spring.
So though I talk, ignore the words and find
In what I cannot say my honest mind.
