Do most people with OCD obsess about things that do not occur in their own lives? Infidelity has not happened in my life or in the lives of those closest to me as far as I know. So it is a mystery that I have this. I know that what I read does not seem to matter in the scheme of things because I am not doing these things, but it has become an unwelcome part of my life for nearly a year now. Anyways, why does the OCD attach itself to certain areas that have nothing to do with my life and sometimes areas that have to do with my life like religion?
