How about the "OCDers" take a look at themselves from a 3rd person POV and notice that what they are doing is completely useless and can be stopped at the source: themselves.

There are drugs that can help achieve the different POV perspective, if their minds aren't strong enough to do it themselves.

Seriously. And also true OCD = hospitalization. A lot of people have picked up the term and apply it to themselves when it shouldn't be.
