Inside the Mind of the Hound From Hell

Where's the end I was promised?
Why was I lied to?
I let them down,
And I'll do the same to you.

I'm a beast inside,
Woman outside.
I keep my sanity on the brink,
Never over the edge.

What happens when a slip up happens?
Who's there to clean the mess?
What happens when I snap?
Will there be no end to my bitter rage?
