Depression is a mental illness that affects a person’s mood—the way a person feels. Mood impacts the way people think about themselves, relate to others, and interact with the world around them. This is more than a ‘bad day’ or ‘feeling blue.’ Without supports like treatment, depression can last for a long time.
Signs of depression include feeling sad, worthless, hopeless, guilty, or anxious a lot of the time. Some feel irritable or angry. People lose interest in things they used to enjoy and may withdraw from others. Depression can make it hard to focus on tasks and remember information. It can be hard to concentrate, learn new things, or make decisions. Depression can change the way people eat and sleep, and many people experience physical health problems.
