Therapy subjects can include a variety of topics, such as fears, aversions, and IDS. Fears are an emotion that is characterized by an intense feeling of apprehension or fear in response to a perceived threat. Aversions are strong dislikes or repulsions to certain things or situations. IDS are the unconscious part of the psyche that contains instinctive and primitive drives. All of these topics can be explored in therapy sessions to help individuals better understand their emotions and behaviors.
