Depression is a common and serious medical condition that affects how you feel, think, and act. It's more than just feeling sad or going through a rough patch—it's a persistent condition that requires understanding and proper treatment. Between 70% and 90% of people with depression respond well to treatment and find relief from their symptoms.
Types of Depression
