Sanity?

You sit and stare,
You hope and pray,
That your mind won't go astray.

Your mind flits back to the time it wandered away;
Leaving you even as you try to make it stay,
And images of your uncontrolled self,
Haunts you with the terrifying reality,
That your safety hung by a thread lost along with your sanity.

You sit and stare,
You hope and pray,
Willing not to relive that kind of day.

Even as you cling to your sanity,
You know somewhere inside your mind,
Is that insidious disease that can overtake you -
any moment, any instance, any circumstance
even when you vigilantly try and guard your mind;

You are your weakest link,
You pray hard you won't yet again sink,
So you torture yourself and continue to think;

Is this the day the nightmare comes out to play?
