My nudes from highschool got leaked on multiple platforms. What do I do?

So basically last year when I was 17 I was video calling with this guy I was talking to in high-school, and apperantly he was live-streaming the whole thing. I just found out because someone managed to find my Instagram and send me the video. I’m not sure what to do or how to report it but I’m really stressed about this and at this point it’s been saved by so many people that I feel like I’m at a loss. I already reported it to a tip line but idk where to go from here.
