Unrequited

Stranded, no volleyball nearby, instead
a red, blood filled vessel lies next to me.
The time between each beat increases
as it slows down to a low
thump...
thump...
thump...
I carved it out of it's cavern myself
and served it up to you overjoyed but
another held your attention and you vanished.
Now, I'm left alone to tend to my wounds.
How am I suppose to stitch myself back up
while stuck, alone on the island of unrequited love?
