Little thorn of mine

You have weakened my walk,
The hurt,
it spreads.
Its blocked my train of thought.
Your full,
Strong,
And won’t back down.
What is your purpose?
I’ve learned your ways,
Yet I am too weak,
To yank you small thorn
From the heel of my foot.
I guess I will forever
Be stuck with the beating pain,
Little thorn of mine.
