Clinical depression symptoms: what should you know?

Depression can affect emotions, the body, and thinking. A person may feel empty, tearful, slowed down, irritable, guilty, or unable to enjoy familiar activities. Fatigue, difficulty sleeping or oversleeping, appetite changes, reduced concentration, and pulling away from others can also occur. Depression commonly presents with these clusters of changes, but an individual symptom such as fatigue or poor sleep has many possible explanations and does not identify the cause on its own.

Keep a brief record of mood, sleep, appetite, energy, concentration, and daily activities, then share it with a clinician. Mention physical symptoms, recent stress, medicines, alcohol or substance use, and any history of mood changes. A general practitioner can assess your health and discuss referral, talking therapy, medication, or combined care. Stay connected with a trusted person and break essential tasks into smaller steps while arranging support.

Arrange clinical care when symptoms persist, return repeatedly, or interfere with work, relationships, hygiene, eating, or sleep. Seek urgent help if you have thoughts of suicide or self-harm, might hurt another person, cannot care for yourself, or feel out of touch with reality. Contact local emergency services or attend the nearest emergency department if safety is uncertain.

Ask which symptoms point to depression, what physical causes should be checked, which treatments are available, how quickly to arrange follow-up, and who to contact during a crisis.
