Depression is a real, but often misunderstood, mental disorder that can be readily treated with both medications and psychotherapy.
Not everyone who is depressed experiences every symptom. Some people experience a few symptoms, some many. The severity of symptoms varies with individuals and also varies over time.
- Persistent sad, anxious, or “empty” mood
- Feelings of hopelessness or pessimism
- Feelings of guilt, worthlessness, or helplessness
- Loss of interest or pleasure in hobbies and activities that were once enjoyed, including sex
- Decreased energy, fatigue, or feeling “slowed down”
- Difficulty concentrating, remembering, or making decisions
- Insomnia, early-morning awakening, or oversleeping
- Appetite and/or weight loss or overeating and weight gain
- Thoughts of death or suicide or actual suicide attempts
- Restlessness or irritability
Some people may also experience certain persistent physical symptoms that do not respond to treatment, such as headaches, digestive disorders, and chronic pain.
A person who suffers from a major depressive disorder (sometimes also referred to as clinical depression or major depression) must either have a depressed mood or a loss of interest or pleasure in daily activities consistently for at least a 2 week period. This mood must represent a change from the person’s normal mood.
