My writing got flagged as 100% AI lol

Hi I'm a high school student. I wouldn’t call myself a writer, but I do enjoy creative writing. So when I got assigned to write a ~1000 word non-linear short story, I was really excited.

I spent hours working on it and was honestly pretty proud of what I came up with. But before submitting, I ran it through an AI detector (because there was a huge AI scandal in my class), and it came back as 100% AI. Now I’m just sitting here doubting everything I wrote lmfao. I keep rereading it, trying to figure out what makes it sound so robotic.

I’d love some advice on what to do. Maybe I’m fine and AI detectors are just dumb? But I still want to make my writing feel more human.

Would it be too much to ask if someone could read my story and help me out?

(lowk panicking cuz this is a big part of our grade and my teacher is really really distrusting rn due to the scandal)

Update: With the help of some users I edited a few sentences and got 68% human! If my teacher ever questions my writing for the 32% AI, I'm going to share her my version history just like many of you suggested. Thank you!
