Well...I guess the time when i felt really angry was when one of my friends betray me. What I did may sound stupid but, for me; that's what could do at least.... I merely blocked them on all Social Media and left a message....
Answer: so i know asking another question isnt what you are looking for, but have you ever felt super mad at someone or like sad about something that happened to you? for example, being backstabbed by a friend is a good one lol. just think abt it and then write five really quick sentences abt it. this has to be from your experience, not anyone elsed because ur teacher is probably gonna ask abt details and you wouldnt know them right? i hope this helped!!☺️
