Swallow Hero

I've a being in my belly
it helps my insides keep
when I am feeling anxious
it helps me fall asleep

it calms me when I'm nervous
it ups me when I'm down
it is a mighty ally
that deserveth to be crowned

it clears my murky thinking
and slows my speeding brain
and keeps my heart from sinking
under deep duress or pain

this being in my belly
I hope it never dies
I hope it keeps on slaying
my dragonic butterflies.
