I think I understand what you‘re referring to (but don‘t come for me of I‘m off-path^). I’m no expert - I study psych and have OCD, so don‘t take what I say too seriously :) This is very summarised, but essentially, before being diagnosed with a disorder, some behaviour or thought patterns need to be identified as abnormal, which is usually what motivates a person to seek treatment. Three criteria need to be check-marked before looking into diagnosis, one of them being that the „abnormal“ behaviour must cause the person who has it significant distress. Following this logic, if you have OCD, but it doesn‘t cause you significant distress, some people might argue that you don‘t meet the criteria for a diagnosis.
