The bad thoughts

They seem to come from nowhere, a dark place most people prefer not to acknowledge. That bad place in your mind where a voice tells you the most terrible things like "I could smash that assholes skull in with my fist fairly easily." Only to just as quickly question myself and my morals. I can't help it, it just happens. I hate myself for some of the things I've thought about. I'd like to think I'm a positive person, though the bad thoughts enter my mind like a leach or a tick that won't come off it occupies my focus and drains my energy. The thought that if it ever came to blows I may seriously hurt someone, and the guilt, the sorrow to come. Thinking as I write, that scares me. I'm not a violent person,i don't think. That evil voice telling me "he'll only hear me if I beat it into him." Just don't let others see it, it'll be fine. I'd never take its advice, even if some people deserve it.
