A mother showing suicidal thoughts, sleep disturbances, and lack of interest typically might be diagnosed with which disorder?

The symptoms described—suicidal thoughts, sleep disturbances, and lack of interest—are highly indicative of Major Depressive Disorder (MDD). This disorder is characterized by a persistent feeling of sadness or a lack of interest in previously enjoyed activities, which directly corresponds to the mother's reported lack of interest. Suicidal thoughts are a significant concern within MDD, often linked to feelings of hopelessness or worthlessness associated with the disorder. Additionally, sleep disturbances such as insomnia or hypersomnia are common among individuals diagnosed with MDD, reflecting the impact of depressive symptoms on overall functioning.

The other options represent different mental health conditions that don't align closely with the combination of symptoms presented. For instance, while bulimia may involve feelings of shame and potential suicidal thoughts, it primarily focuses on eating behaviors and does not typically emphasize sleep disturbances or generalized lack of interest in life. Dissociative amnesia relates more to memory loss associated with traumatic or stressful events, rather than the emotional and behavioral symptoms detailed in the question. Similarly, panic disorder with agoraphobia is centered around panic attacks and anxiety in specific situations, without the core depressive symptoms highlighted here.
