Can ocd be outgrown?

Ovrcome not outgrown: Generally ocd does not go away on its own, which it seems you are asking when you use the word "outgrown." exposure / response prevention (erp) is a well validated treatment for ocd. It involves working w a therapist who helps you expose yrself to the triggers for the compulsive behavior, then preventing the compulsive response. Over time the urge to do the behavior is more easily dismissed.

Meds and therapy: Meds (usually antianxiety medications, but not always) combined with therapy with a clinician who specializes on OCD is the best combination to treat OCD, typically. Cured is not a word that I would use to describe optimal results. Symptom reduction is part of it, but the emotional management that is the root of it should be the focus. If the anger/fear is resolved then the behavior will decrease
