Difficult Teen Therapy

Son had begun to have issues as he hit teens, and starting being depressed and acting out, giving parents a hard time. Parents send him to a therapist, who uses hypnotism. He just means to get him to relax, understand his parents have his best interests in mind and trust them. Mom notices he seems to be getting more attentive to them, wanting to please, and be nice.
