SADNESS IS NOTHING BUT A SERIES OF NEGATIVE FEELINGS ARISING OUT OF OUR EXPECTATIONS, IF OUR EXPECTATIONS ARE NOT MET WE FEEL SAD.
KEEP TRYING TO KEEP A STRONG CHECK ON YOUR EMOTIONS.
KEEP NEUTRAL AND NON EMOTIONAL AND SADNESS WILL DISSAPPEAR WITHIN 30 TO 45 MINUTES, TRY DEEP BREATHING AND LIGHT BODY MOVEMENTS.
GOOD LUCK
