Depression is a common but serious mood disorder characterized by persistent feelings of sadness, hopelessness, and a lack of interest or pleasure in activities that were once enjoyable. It can affect a person's thoughts, behavior, emotions, and physical well-being. Symptoms of depression can vary in intensity and may include:
- Low mood or sadness
- Loss of interest in activities
- Changes in appetite or weight
- Sleep disturbances (insomnia or excessive sleeping)
- Fatigue or low energy
- Difficulty concentrating or making decisions
- Feelings of worthlessness or excessive guilt
- Thoughts of death or suicide
Depression can be triggered by a combination of genetic, biological, environmental, and psychological factors. It is different from normal feelings of sadness or grief and often requires treatment, which may include therapy, medication, lifestyle changes, or a combination of these approaches. If someone is experiencing depression, it is important to seek professional help.
