Step-by-step explanation:
The symptoms described in the question are indicative of Major Depressive Disorder (MDD). MDD is a mood disorder characterized by persistent feelings of sadness, irritability, guilt, and loss of interest/pleasure in activities. Other symptoms include changes in appetite, sleep disturbances, and difficulty concentrating.
It is important to note that a diagnosis of MDD should be made by a healthcare professional based on a comprehensive evaluation that takes into account the individual's overall mental and physical health.
Treatment for MDD may include therapy, medication, or a combination of both. Therapy options such as cognitive-behavioral therapy (CBT) can help individuals develop coping skills and address negative thought patterns. Medications like antidepressants may also be prescribed to help regulate mood.
