In one of my psych courses the professor noted a study (not sure of the source, this was closing in on twenty years ago now) that while psychotherapy had pretty good efficacy for certain things, it was equivalent with "talk openly with your friends about it" in most metrics. A therapist is great for providing specific strategies to address particular challenges (for issues like PTSD, for example, a therapist can help to manage an exposure therapy approach) but after a point you're kinda just paying through the nose for somebody to professionally emulate you having a healthy friendship with a well-adjusted person.
