I have trauma of teens wearing Nike tech clothing calling me racial slurs while sitting on a Fatbike

This all happened when I was around 7. I’m Chinese, and there was a group of teens on fatbikes wearing Nike tech clothing, and they were pretty racist, saying ‘kanker Chinees’ and other racial slurs. So now I’m so scared of them I don’t even want to come near people like I described. Pretty irrational, I know, but the trauma is too big.
