The symptoms of depression vary widely, such as sleeping too much or too little. This is one reason why diagnosing depression can be a challenge. Other symptoms include lost interest in favorite activities, feeling hopeless, and under-or overeating.[1] Symptoms may also vary by sex. For example, men with depression report higher rates of anger, aggression, substance use, and risk-taking compared to women.[2]
