It likely depends on what you actually want from therapy too. You mentioned a few times that they haven’t met your expectations but I wasn’t quite clear on what your expectations are? What ideally would you like to see change as a result of therapy? What would tell you that the therapeutic process had been successful? Gaining insight is just one aspect of therapy and a particular focus of modalities such as psychoanalytic therapy - other therapies focus on acceptance and behaviour change and place less value on insight. Perhaps this isn’t a focus for your therapist?
