Not in control

The best way to describe my problem is by showing you.

The moon comes up, and the pain engulfs my body, reddening my eyes. My teeth grow much longer. My nose becomes a black snout. My legs become stretched and bony, but strong and nimble. My finger and toenails form into full on claws, sharp as knives, hard as diamond. My fear becomes at its highest peak as the black and silver fur forms all over my body. I finally let out my kept in agony as a howl, but really it is a scream for help. Help me. Please.
