Especially considering this is a post about mental health, can we please quit labeling being picky as OCD? OCD is a serious condition, not a "haha I'm picky" joke.
Have you looked into OCPD? (Obsessive Compulsive Personality Disorder) From my relatively uninformed knowledge on the subject, that sounds closer to OCPD. (Of course, talk to a licensed health practictoner, not a procrasting software engineer)
