Recreate yourself as a Gothic villain. If you can, draw your caricature even. But, write your description, a profile of who you would be, what you look like, how you act, if you were an evil, wicked goth type.
It’s a lot of fun. I’ve written myself a whole scenario where I am mean, evil, vicious and cruel. Talk about a way to relieve your stress! Being nasty, on paper, is great fun.
