@Noonespecialanyways if you really want to make a chapter or story, go for it! The beauty of Wattpad is that you don't necessarily have to publish the stories you write. Make some drafts of ideas/memories you have. Maybe even add some things that didn't really happen or things you wish happened to make a new story, like I did with The Girls' Locker room series I wrote. Use your imagination. So I would say go for it; start writing what happened in your experience, and then see where your brain and heart takes you.
