Good evening.
Since there are no specifics to the assignment, it is very difficult for me to say exactly what your instructor is looking for. Generally, almost all essays are "personal essays" as they contain your specific opinion, thoughts, and/or feelings about a specific topic. It mostly ends up being a very strong opinion piece about something, because there should be no effort to objectify your thoughts on the topic. There are usually no cited resources, no secondary opinions, and there is no concealment that this writing is your opinion.
I hope this helps.
