My Plagued Heart

You are the Black Death of my heart,
You came and loved me,
Or I thought you did,
The you left me with this horrible disease,
This horrible disease you left me is slowly consuming my heart,
That is no longer whole but broken,
You left my heart with a plague, a deadly plague,
That would kill the feelings I had for you
This plague you left on my heart is the Black Death or the Bubonic Plague
