Lately I have been having thoughts about doing something a rational person would never do. I have posted a thread about an example of what I have been thinking about and someone said that I might have OCD. My thoughts are things like: "What if I could use this knife to murder someone?" or "What if I could turn he steering wheel while someone is driving?" Sometimes thee thoughts come with disturbing or mild images of what would happen, but most of the time there isn't. I am a bit worried and unsure of what to do to stop these thoughts. I have been blocking them out but they keep on coming back. Do I have OCD? Or is it just me?
