how do i know i have depression

To know if a person has depression, key signs and symptoms to look for include persistent feelings of sadness, emptiness, or hopelessness that last most of the day nearly every day for at least two weeks. Other significant symptoms are loss of interest or pleasure in activities, changes in appetite or weight, sleep disturbances (either insomnia or oversleeping), low energy or fatigue, trouble concentrating or making decisions, feelings of worthlessness or guilt, irritability, and recurrent thoughts of death or suicide. These symptoms often cause noticeable problems in daily functioning, including work, school, and relationships. Depression can also show in physical symptoms like unexplained aches and pains. If these symptoms persist and interfere with life, it is important to seek help from a healthcare provider or mental health professional.
