Being a neat freak isn't OCD: psychologist explains the difference

Liking things tidy, like Monica Geller in Friends, does not mean you have OCD, says clinical psychologist Dr Uma Maheswari Ganesh. Perfectionism is a personality trait, while OCD is a clinical disorder driven by fear or intrusive thoughts that something harmful will happen. The warning sign is when order becomes an urgent compulsion that overrides everything else. Avoid self-diagnosis.
