Yes, T has been in therapy themselves--BUT as someone who has seen some really really weird therapists over the years and has had some really really weird professors and supervisors while studying psychology, I know all too well that "being in therapy" doesn't mean that one is "cured"

I think the best indicator of whether or not one has benefited from their own therapy is a therapist who demonstrates all the great qualities we all discuss here on the forum: a good listener, compassionate, consistent, infinitely calm and unflappable, empathic, adaptable, own their own part in the relationship and nonjudgmental . . . and even then, it doesn't mean that we'll all be able to connect and find therapy a productive undertaking. Also, I truly believe that there are people who demonstrate these qualities and who have never even needed therapy--they were raised in a manner that instilled those qualities in them from childhood and they possess a genetically unflappable temperament (lucky dogs!)
