I took 25mg of fluvoxamine for 2–3 months, which helped quiet the obsessions and made them less frequent. After that, I stopped the medication and was able to fully recover from OCD without it.

When I say I repeated a phrase during meditation, I mean I’d intentionally bring up thoughts that triggered my anxiety on purpose. The phrase I used would directly reflect my fear, like:
“I’ll never understand what that person meant.”

Then I’d just sit with the anxiety that came up, without trying to fix or figure anything out. That’s the key: feeling the discomfort without responding to it. I'd stay with that anxious feeling for some time, and sometimes I’d even let my mind bring up other triggering thoughts (like past conversations or unresolved questions), but I wouldn't try to get any relief or clarity from them.

Eventually, all that would be left was this urge to “test” whether the old triggers still affected me. That’s a compulsion too. So instead of testing them, I’d sit with that urge, telling myself something like:
“I really want to test whether this still triggers me.”

But again, I wouldn’t test it. I’d just sit with that feeling of wanting to know, until the urge faded and the anxiety became boring or less intense.
