General & Preventive
  • What exactly is depression?
    MedlinePlusMay 2026

    Depression is a serious mood disorder that's more than just feeling sad for a few days. It affects how you think, feel, and do everyday activities like sleeping, eating, and working, and it often needs long-term treatment to get better.

  • How does depression affect my daily life?
    MedlinePlusMay 2026

    Depression can make basic daily activities feel very difficult or impossible, like getting out of bed, eating meals, or focusing at work or school. It affects your mood, energy, and how you see yourself and the world around you.

  • Can depression happen suddenly or does it build up over time?
    MedlinePlusMay 2026

    Depression can develop suddenly or gradually over time, depending on the type and what's causing it. Some people notice it starting after a stressful event, while others find it creeps up slowly without a clear reason.

  • Is there a difference between sadness and clinical depression?
    MedlinePlusMay 2026

    Yes—sadness is a normal feeling that comes and goes, but clinical depression lasts much longer (at least two weeks) and makes it hard to do everyday things. With depression, you might feel sad, empty, or lose interest in things you normally enjoy, even when nothing bad happened.

  • Are there different types of depression I should know about?
    MedlinePlusMay 2026

    Yes, the most common types are major depression (severe symptoms lasting at least two weeks) and persistent depressive disorder (milder symptoms lasting at least two years). Other types include seasonal affective disorder, which comes and goes with the seasons.
