Depression is more than feeling sad or stressed for a few days. It’s a persistent shift in mood, energy, and thinking that lasts two weeks or longer and interferes with daily life. If you’re asking this question, it’s worth paying attention to your symptoms.

Common Signs of Depression

Ask yourself:

• Do I feel sad, empty, or hopeless most of the day, nearly every day?
• Have I lost interest in hobbies, friends, or activities I used to enjoy?
• Am I sleeping too much or struggling to sleep, even when exhausted?
• Do I feel tired all the time, no matter how much I rest?
• Have my appetite or weight changed without trying?
• Do I feel worthless, guilty, or like a burden to others?
• Is it hard to concentrate, make decisions, or remember things?
• Have I had thoughts that life isn’t worth living?

You don’t need to have all these symptoms. But if you’ve had five or more—including either persistent sadness or loss of interest—for at least two weeks, it could be clinical depression.

Physical signs count too: unexplained aches, digestive issues, or constant fatigue can also point to depression, especially in men.

What to Do Next

Only a doctor or mental health professional can diagnose depression. But noticing these signs is a powerful first step. Track your symptoms for a week or two. Then reach out—whether to your primary care provider, a therapist, or a trusted person who can help you find support.

Depression is common, treatable, and nothing to be ashamed of. Asking “How do I know if I have depression?” might be the beginning of your healing.

You don’t have to figure this out alone. Help is available—and recovery is possible.
