is a fairly common problem where people experience ‘obsessions’, recurring unwanted thoughts which are difficult to stop, and ‘compulsions’, rituals of checking behaviour or repetitive actions which are carried out in an attempt to relieve the thoughts. Source: www.rcpsych.ac.uk/info/glosConds.htm

After giving the formal and scientific definition of what OCD is, I would like to mention that most people who suffer from OCD have their own definitions of OCD, of course a definition affected by their OCD.
That is, they usually think that their OCD is not right. There have to be a more accurate OCD than they have.
Just from this point, it is not difficult to imagine the anxiety and stress that OCD may bring on any given day.
