Sadness is an unpleasant state of mind that usually presents itself in external indicators such as tears, pessimism, depression, lack of spirit, low self-esteem, and other unsatisfying states of mind.
Sadness is a common emotion that can range in intensity from temporary sadness that fades when the underlying cause is removed to deep or intense grief that lasts days or weeks. It can be a sign of a more complex problem, such as depression, and may require professional assistance.
