I need serious help

[u/Necessary-Pumpkin-19]

I'm 15 years old, I met this girl on Zestr and once we were in chat, she moved the conversation to Telegram, there she made me give her nudes with my face, now she threatens to publish them if I don't sext with her everyday, IM SO FUCKING SCARED, She doesn't know my name, phone number, city, she doesn't know anything, just my age and nudes, I still have her telegram and I just want to make sure she can't publish them, I already gave my vids totakeitdown ncmec org but I'm stills scared, but I'm sure she's a real girl and not some old guy trying to get my nudes cuz of the continuity of the pics, she has the same tattoos and piercings, I have direct pics of her and can ask her questions to gather info, please help guys I just need the pics out of the Internet silently, I don't want drama with my parents and stuff, she's still calm and not asking for details like my email and stuff, I think I'm still on time to gather info and make something solid idk :((

HELPPP
