I think your topic will work as long as you narrow down the insights and narrative that you want to convey. While your experience is not unique the way you experienced it is unique. Highlight what makes you, you and enjoy the opportunity to be some combination of passionate, vulnerable, open, funny, etc.
Upon completion of the essay reread it, and rather than asking yourself what did I tell the reader, ask yourself what you made the reader feel. Effective written communication goes beyond fact sharing and is ideally some combination of compelling, thought provoking, insightful, etc. Ask yourself honestly if your essay accomplishes what you set out to have it accomplish.
I would also suggest some obvious areas for focus when trying to be persuasive and impressive in written form. Avoid typos and use proper grammar, be attentive to details, answer the question that is asked , take your time responding and lastly be conscious of your audience and have a sense of context.
Hope this helps and good luck!!
