Define Depression.

Depression is a mental health disorder characterized by persistent feelings of sadness, hopelessness, and a lack of interest or pleasure in activities. It goes beyond the normal fluctuations in mood that people experience and can significantly impact one's daily functioning and overall well-being. Key features of depression include:

1. Persistent Sadness: Individuals with depression often experience a pervasive and prolonged sense of sadness or emptiness that persists for most of the day.

2. Loss of Interest: A notable decrease in interest or pleasure in activities that were once enjoyable is a common symptom of depression.

3. Changes in Sleep and Appetite: Depression can lead to disruptions in sleep patterns, including insomnia or excessive sleep, as well as changes in appetite, resulting in weight loss or gain.

4. Fatigue and Low Energy: Individuals may feel persistently fatigued, lacking the energy to engage in routine tasks or activities.

5. Difficulty Concentrating: Depression can impair cognitive function, making it challenging to concentrate, make decisions, or remember information.

6. Feelings of Worthlessness or Guilt: Individuals with depression often experience feelings of worthlessness, guilt, or self-blame that may be disproportionate to the situation.

7. Physical Symptoms: Some individuals may experience physical symptoms such as headaches, digestive issues, or chronic pain alongside their emotional distress.

Depression is a common and treatable condition, and interventions often include psychotherapy, medication, or a combination of both. Seeking professional help is essential for accurate diagnosis and effective management of depression.
