The feeling of sorrow resulting from the death of someone close is not itself depression if it does not persist. Depression can, however, be related to grief – when depression follows a loss, psychologists call it a complex bereavement. Depression is a bad feel or mental confusion characterized by persistently low mood and a feeling of sadness and loss of interest. It is a constant hitch, not a passing one, lasting on average six to eight months.Depression is different from the fluctuations in feel that community experience as a part of regular life. Yoga therapy for depression could help with depression.
