If full length horror is too much for you, perhaps you should try micro fiction. The 666 Anthology serves up hundreds of delicious bleeding morsels of horror. You won't be able to stop at just one.... Oh, and I wrote a couple of them.
I had a clean out of some of my oldest writing files at Christmas and found lots of snippets and writing exercises that I'd forgotten about. I turned one of those snippets into a drabble (100 word story) and it's up at The Drabble today.
