Im worried and confused about what happened to me and my mom

I was walking home with my mom and I after grocery shopping, and some random guy took out his phone and started filming us. Ive never had someone point a camera so directly in my face before it felt terrifying. He then shouted “i’ve got more” and called us the n word, he also crossed the street and yelled more things but I didn’t pay attention cause my brain shut down and my mom wants to know so badly because she doesn’t understand english very well. That was so confusing and was completely unprovoked. Im kinda worried he will post us online or something or if I should be concerned about my family and I’s safety since this happened in a not so populated area of queens,ny. Im scared to go outside now too for a bit. What should I do?
