A psychologist would be appropriate for this study case. The psychologist will help the teen who has experienced a traumatic event. The therapist will observe and guide how the teen wants to take the session but in an appropriate way. The therapist will offer security for the teen to feel comfortable and this will tell in a couple of sessions for the teen to reach to that stage. After a couple of sessions, the therapist will want to clear out the teen’s thoughts of what happened in the event. On the last session, the therapist will ask the teen to remove the fears and worries and the negative thoughts that are running through their mind.
