Do you need help with the topic, or how to write it?
With the topic, its asking you about it personally. So you’d want to just reflect, and see if there was an experience that you can relate to with the question.
To write it out, just pretend you’re talking to a friend about it. Probably at least a paragraph or two, and with detail about certain parts of it. What I mean by detail, I mean by adding adjectives of adverbs that bring the emotion of regret and a negative emotion of your choice that fits into the experience you chose.
