It's so hard trying to figure out compulsions that you are doing unconscious... I think I'm trying to figure out more of those unconscious compulsions ( feeling checking, telling my brain what I rly want, nitpicking my partner etc). What is the best way to figure out your unconscious compulsions?

I would say to try your best to not analyze this as it can lead to emotional reasoning. It really begins with consistently practicing foundational steps whatever that looks like for you. Educating yourself, learning with a NOCD therapist, attending webinars, etc. I read an article yesterday by a Dr. Greenberg about rumination and it really covers how even asking things like this are typically forms of rumination and analyzing. So instead how about you sit with the doubt, discomfort, anxiety, and get back to whatever it is you were doing before. Were you reading, eating, exercising?… good, go and do something for yourself, not to avoid thoughts…but to focus on what actually matters to you.
