1. Write Your Personal Narrative as a Story
As a story, it must include an introduction, characters, plot, setting, climax, anti-climax (if any), and conclusion. Another way to approach it is by structuring it with an introduction, body, and conclusion. The introduction should set the tone, while the body should focus on the key point(s) you want to get across. The conclusion can tell the reader what lessons you have learned from the story you've just told.
2. Give Your Personal Narrative a Clear Purpose
Your narrative essay should reflect your unique perspective on life. This is a lot harder than it sounds. You need to establish your perspective, the key things you want your reader to take away, and your tone of voice. It's a good idea to have a set purpose in mind for the narrative before you start writing.
Let's say you want to write about how you manage depression without taking any medicine. This could go in any number of ways, but isolating a purpose will help you focus your writing and choose which stories to tell. Are you advocating for a holistic approach, or do you want to describe your emotional experience for people thinking of trying it?
Having this focus will allow you to put your own unique take on what you did (and didn't do, if applicable), what changed you, and the lessons learned along the way.
3. Show, Don't Tell
It's a narration, so the narrative should show readers what happened, instead of telling them. As well as being a storyteller, the author should take part as one of the characters. Keep this in mind when writing, as the way you shape your perspective can have a big impact on how your reader sees your overarching plot. Don't slip into just explaining everything that happened because it happened to you. Show your reader with action.

You can check for instances of telling rather than showing with ProWritingAid. For example, instead of:
"You never let me do anything!" I cried disdainfully.
Try:
"You never let me do anything!"
To this day, my mother swears that the glare I levelled at her as I spat those words out could have soured milk.
4. Use "I," But Don't Overuse It
You, the author, take ownership of the story, so the first person pronoun "I" is used throughout. However, you shouldn't overuse it, as it'd make it sound too self-centred and redundant. ProWritingAid can also help you here – the Style Report will tell you if you've started too many sentences with "I", and show you how to introduce more variation in your writing.
