Now, let’s define disappointment.

It comes from prefix “Dis” which is denoting the removal of something and thus expresses negation.

You will never know what it is until you feel sadness, dismay, heavyheartedness, experience failure or misfortune in your life. Stress, anxiety, or worst, depression.

The main causes usually came from an unpleasant event in your life, things, or even came from people that are close to you. But the most painful disappointment is coming from yourself.
