Depression

What depression actually is

Depression is more than feeling sad. It’s a persistent state in which mood is low, interest in things you used to enjoy fades, energy drops, sleep and appetite shift, and ordinary tasks feel heavy. To meet criteria for major depressive disorder, these symptoms have to be present most of the day, nearly every day, for at least two weeks, and they have to interfere with function.

It’s a recognized medical condition. The brain’s mood-regulating circuits, the body’s stress response, sleep, hormones, and life circumstances all play a role. Depression isn’t a sign that something is wrong with your character. It’s a sign that something specific is happening in a system that can be treated.

What depression can feel like

People describe it as flat, gray, heavy, or empty more often than they describe it as sad. Things that used to be enjoyable feel like nothing. Decisions get harder. Concentration drops. Sleep changes, often more than expected, or much less. Appetite changes. The body feels tired even after rest. Many people describe thinking that runs in negative loops.

In severe depression, thoughts about death, dying, or not wanting to be alive can show up. Those thoughts deserve immediate attention and a conversation with a professional.

What depression isn’t

Depression isn’t laziness, isn’t weakness, and isn’t a “phase you should snap out of.” It also isn’t always triggered by an event. Some depressions follow a clear loss or stressor. Others arrive without one.

When to seek professional care

If low mood, low interest, or low function have lasted more than two weeks, talk to a clinician. If thoughts about death or self-harm are present, talk to someone today. Effective treatments exist, and most people who get evaluated and treated do get better.
