Due to OCD being about control and familiarity, it seems like one of the most difficult times would be around when younger kids leave for freshman year of college. Not being around their families and on their own for the first time can open up some serious OCD hell gates (not in a scrupulosity type of way). IOCDF, nOCD (TreatMyOCD), and The Mighty all do good jobs of providing some tips, also with posting stories on their blogs about successful transitions and maintaining life sanity while dealing with OCD during this time in life.

Also, you can probably imagine that there aren't enough "ocd specialists" in college atmospheres on campus.
