Depression isn’t a weakness, nor is it something that you can simply “snap out of.” Depression, formally called major depression, major depressive disorder or clinical depression, is a medical illness that involves the mind and body. It affects how you think and behave and can cause a variety of emotional and physical problems. You may not be able to go about your usual daily activities, and depression may make you feel as if life just isn’t worth living anymore.
Effective diagnosis and treatment can help reduce even severe depression symptoms. And with effective treatment, most people with depression feel better, often within weeks, and can return to the daily activities they previously enjoyed.
Signs and symptoms of depression
Symptoms of depression include:
- Loss of interest in normal daily activities
- Feeling sad or down
- Feeling hopeless
- Crying spells for no apparent reason
- Problems sleeping
- Trouble focusing or concentrating
- Difficulty making decisions
- Unintentional weight gain or loss
- Being easily annoyed
- Feeling fatigued or weak
- Feeling worthless
- Loss of interest in sex
- Thoughts of suicide or suicidal behavior
- Unexplained physical problems, such as back pain or headaches
Depression symptoms can vary greatly because different people experience depression in different ways. A 25-year-old man with depression may not have the same symptoms as a 70-year-old man, for instance. For some people, depression symptoms are so severe that it’s obvious something isn’t right. Others may feel generally miserable or unhappy without really knowing why.
