Final answer:
Grace most likely has Major Depressive Disorder (MDD), as her symptoms align with the diagnostic criteria for this mental health condition, characterized by prolonged sadness, withdrawal, and loss of interest in previously enjoyed activities. Correct answer is c) Major Depressive Disorder (MDD).
Step-by-step explanation:
Grace is most likely experiencing Major Depressive Disorder (MDD). This mental illness is characterized by a persistently depressed mood, changes in sleep and appetite, loss of pleasure in activities, and social withdrawal. Major depression is not just occasional sadness; it's a long-term condition that significantly affects a person's everyday life and requires treatment.
Given Grace's symptoms, such as intense sadness, changes in sleep and diet, social withdrawal, and loss of interest in activities that used to bring her pleasure, she fits the diagnostic criteria for MDD more closely than the other disorders listed. It is different from normal sadness or grief, as it lasts for a longer period of time and significantly impacts daily functioning. Treatment for MDD may include psychotherapy and medication. So, the correct answer is c) Major Depressive Disorder (MDD).
