The question above wants you to write a text about your personal situation. For that reason, I can't write this text for you, but I'll show you how to write it.
As shown in the question above, you may recall a time when you felt humiliated, mistreated, disrespected, and unappreciated. Remember the feelings you felt at that moment and the reasons that made this moment happen.
After remembering this moment, you can write the text as follows:
Briefly present this moment, how it happened and why it happened.
Show the feelings you had at the time and why this moment was meaningful to you.
Show how you acted at that time and whether or not you regret having acted that way.
Show how the way you acted represents your personality.
