Many researchers, sufferers of OCD and therapists have considered OCD to be an illness about ‘doubting‘. Even though, most of the time, an individual suffering with OCD knows rationally that their obsessions are unrealistic, or are about overestimations of danger, or about misappraisals of situations, they struggle with “yes but” or “what if” something does or can happen? It can be very difficult and sometimes counter productive to try and talk or rationalize one’s way out of these doubting obsession.

What often appears to be very time-consuming for many individuals with OCD are the constant internal fights with their doubt. Even when an OCD sufferer knows that their fear is very unlikely to happen to them, they still consider the possibility of it happening.
