In this song, the "therapist" being referred to is a "psychotherapist." Therapists are licensed mental health professionals who specialize in helping people develop better cognitive and emotional skills, reduce symptoms of mental illness, and cope with various life issues or trauma. Therapists focus on mental health. Meanwhile, doctors are also licensed medical professionals but they also deal with a variety of health issues outside of mental health. Ex: Many adults see therapists to deal with their childhood trauma. Ex: I have been seeing a therapist to help me deal with the stress in my life. Ex: I sprained my ankle, so I went to see a doctor.
