I am not sure if psychotherapy is useful either? I would reach a plateau with a therapist where it was not really helpful any more. I could get the same or better results for free by talking to a close friend or family member.
Also, the psychotherapists, counselors, mental health professionals I know all have major issues such as cluster B personality disorders like narcisscistic personality disorder, eating disorders, drug addiction, major depression with actual suicide attempts, anxiety/panic attacks, etc.
Nobody is perfect but it does make me wonder why these people are giving advise to clients about mental health, therapy, etc.
