A Writer's Block

Now I'm resting in my room,
my brain has fallen in doom
thoughts left flying like a flock
oh my God,  a writer's block!

I can even hold my pen,
shrugging nonsense in my den
rhyme gets harder than a rock
oh my God, a writer's block!

scroll the pages up and down
poor, my muse has been mown
my prose now needs a doc
oh my God, a writer's block

I can't think anything else
to complete this rhyming verse
this short poem received a knock
down by my writer's block!
