What is a Depression?
Depression is a common mental health condition where a person feels very sad, empty, or hopeless for a long time (usually more than 2 weeks). It is not just sadness — it affects how a person thinks, feels, behaves, eats, sleeps, and functions in daily life.

A detailed conversation about mood, thoughts, behavior, and life changes
Screening tools/questionnaires like PHQ-9 or HAM-D
Physical exam and blood tests to rule out medical problems (e.g., thyroid issues, vitamin deficiencies)
Mental health evaluation to check for other conditions (e.g., anxiety, bipolar disorder)
