Girl In A Different Country Blackmailing Me With Nudes (im A Minor)

So i (US) got into relations with a girl (France). I broke up with her after not even 2 months because she was CRAZY, im talking literally psychotic. Anyways, i regrettably missed having someone to talk like that (just like someone who doesn't have ties to people irl) After awhile of talkling again she started asking for nudes again and i wont lie i was lonely and yk and i sent them (i know bad call) but it wasnt the first time shes seen them. Kinda recently (like a month ago) she asked for nudes again but threatened to leak my nudes if i didnt, turns out she found my insta, which led to my school and all of my friends. She constantly asks and when i say no, she threats it, and out of fear i send. Today she asked and i said No, i had been distancing myself from her recently and she threatned it saying "Im not in the mood" "send" stuff like that. I very clearly stated it was illegal and i dont want o keep doing it but she just says "i dont care". Shes asleep but told me if i didnt send by when she woke up she'd leak it.

EDIT: She also has admitted to stabbing a kid when she was like 8 and lying about it. She said she doesnt THINK hes dead though

Im really tired of dealing with it so i want to know, can i get her in some deep trouble if she leaks it? And what would the general process be like. Also, what the punishment for both me and her would be. If she leaks it, it'd be to at LEAST 60 people (the people on my insta), i dont know if shed go as far to show my whole school

Thank you
