Why am I sad?

I ask myself that question all the time,
And I never seem to have a definite answer
Besides the occasional
"I don't know."

But what if the reason
Was that there were actually too many reasons,
And they somehow merged into one big mess,
And so I could never really identify which was the actual problem?

Why am I sad?

Perhaps I will never really know.

Until then, I'll be drowning in this sadness.
