A collection of poetry, grim and dark

I live my life under constant strain
Forever in fear of the beast inside me
I have to keep it from my friends
I don't want them to worry
And if it gets out, their lives will be the first it ends
For now though, I keep it contained

Everyday I feel it growing
It tells me to commit terrible acts
To hurt my neighbors, make them feel pain
Drown them, stab them, chop them with an ax
To grind their bodies up and flush them down the drain
Signs of its escape are showing

In the end the beast was more than I could take
But I find that it's not so bad, now I'm free
I feel alive, I'm thinking clearly for the first time ever
For the first time in my life, I feel truly happy
I feel so giddy, I could just laugh forever
I'm having a friend over, we're going to make cupcakes...
