Depression symptoms differ from person to person. Some may only have a few, while others may have many. Symptoms change over time. The most common are:

• Feeling sad, empty, or hopeless—these are less common in older adults, children, and adolescents
• Feeling guilty, worthless, or helpless
• Agitation, worry, or anxiety
• Mood changes
• Trouble sleeping, waking up too early, or sleeping too much
• No desire for hobbies, for social engagements, or to be around your friends or family
• Feeling tired
• Having general pain in the stomach, head, muscles, and joints
• Problems thinking clearly
• Eating habits change
• Weight gain or loss
• Loss of interest in sex
• Thoughts of death or taking your own life—with or without trying it

Depression can interfere with your family or your school or work life. It can also cause problems in how you relate to other people. If you have any of these problems for 2 weeks or more, call your doctor.
