To make the phenomenon of sadness happen, you have to give energy. That’s why after sadness you feel so dissipated, drained. What happened? — because in depression you were not doing anything, you were simply sad. So why do you feel so much dissipated and drained? Out of sadness you must have come full of energy — but no. Remember, all negative emotions need energy, they drain you. And all positive emotions and positive attitudes are dynamos of energy; they create more energy, they never drain you.
