2. Behavioral approach: This approach aims to modify behaviors associated with depression. The therapist may work with William to gradually increase her engagement in activities and encourage her to set achievable goals. The therapist may also incorporate behavioral activation techniques to increase positive reinforcement and establish daily routines.

3. Pharmacological approach: When severe depressive symptoms are present, a therapist might recommend a combination of psychotherapy and medication. A psychiatrist or medical doctor could prescribe antidepressant medication to help alleviate some of the symptoms and regulate neurotransmitter levels in the brain.
