What are your biggest compulsions and obsessions if ocd?

Those That Impair. The worst symptoms of OCD (obsessions and compulsions) are those that cause the greatest impairment in a person's ability to engage in life. One patient comes home and spends 8 to 10 hours straightening the fringe on his carpet and is able to hold a normal job. Another patient cannot hold a job because of chronic tardiness as he must park his car in an exact manner and continues this for hours.
