According to the Diagnostic and Statistical Manual of Mental Disorders (DSM), depression is a mental disorder marked by sadness, isolation or despair that lasts for a long time. People with depression don’t just feel the sadness we all feel every now and then. It’s much darker and harder to deal with.
Statistics show that 6.7 percent of the US population is affected by depression. That’s 15 million people—and it’s only an estimate reported by the National Institute of Mental Health. The real numbers could be much bigger, seeing as most people don’t get the treatment they need to manage their depression.
2. Sudden changes in sleeping habits. The person dealing with not enough sleep or too much sleep might look constantly exhausted. Not everyone who has depression deals with this, but it’s a common symptom.
3. Easily irritable, angry or upset. A person with depression might not realize that they’re doing this. Their reactions to small amounts of stress can be to get irritated quickly when there’s no need to.
4. Change in productivity. Another symptom of depression is a diminished ability to think clearly or concentrate in everyday tasks. Someone with depression might start making a lot of mistakes that they never made before.
