You need to put a few more comma's in here and there for example
A misunderstanding can lead to misunderstood love.
But a comma between Misunderstood and can. I'm sure you'll figure out the rest but uh heres where else you need them.
The Sorrow unthinkable (between sorrow and unthinkable)
My heart a thousand pieces(between heart and a)
My mind a darkened abyss of thoughts (mind and a)
My spirit a field of destruction(spirit and a)
Other than that the poem was well written!
