What is Major Depressive Disorder?

Major depressive disorder (MDD) is a mental health condition that causes feelings of sadness, emptiness, and hopelessness that last for a long time. People with MDD may lose interest in activities they once enjoyed, have trouble sleeping or sleep too much, feel tired all the time, and have

difficulty concentrating. They may also have physical symptoms like headaches or stomachaches. Remember, MDD is a treatable condition. With the right support and care, it's possible to manage symptoms and feel better.
