"Pure O": the rituals no one sees

People call this "Pure O" (purely obsessional). The name is a bit misleading: there are almost always compulsions. They're just invisible.

Mental rituals look like this

• Reviewing: replaying a conversation or memory to make sure nothing bad happened
• Analyzing: trying to figure out what a thought "means"
• Neutralizing: replacing a bad thought with a good one, or saying a phrase in your head
• Checking feelings: testing whether you still feel anxious, attracted, guilty
• Praying or counting in a specific way
• Seeking certainty: needing to be completely sure before you can move on

Why they matter

Mental rituals work exactly like washing or checking: they bring short relief and keep the loop going. Many people don't realize they're compulsions, so they never mention them to a doctor.

What helps

ERP treats mental rituals too. With a therapist, you practise noticing the ritual and letting the thought be there, without solving it. It feels strange at first. Over time, the thoughts lose their power.
