If not?

If I close my eyes, I stare into the abyss of darkness. Just a little step over and I am one with the darkness. Instead I just swing back and forth, not here not there.  In between. Let the music crawl slowly up my spine.
Let the wind howl away the worry.
It is a fight I cannot fight. I stare into the shadows all around, hope to see the faces I know.  Instead there are just glimpses of maybes and madness waiting for his time to come. What is there to stop me from giving into it? Let the madness take me, while I am still sane.
I let the music slowly crawl up my spine.
I let the wind howl away the worry.
Back and forth I go.
Who will stop me?
Who will take me, before the madness does?
