Unseasonable

I feel a chill, although I know the heat
Is turned up higher than I wanted it.
Deep in my bones, rising from my feet
I feel a shiver, ending in the pit
That seems to have replaced my stomach. Why?
I cannot tell, except, perhaps some worry
Has, all of a sudden, on the sly,
Slipped past my guards, and in a desperate flurry
Of discontent, uses my nerves as tools
To make me so uneasy, and so cold.
Whatever is the cause, it clearly fools
My senses, which I wish I could have told
To be suspicious of such sudden chills;
Instead I shiver as the worry wills.
