My freind is hellbent on convincing me I'm gonna die for a prank

Ok so, im f (17) she's f(15), for the past few days she's been telling me a cooked up story that there is a cult for our schools principal, and she made me and a freind eat a dry ramen now she's going around telling us we're gonna die in 4 weeks due to the cult activities, obvs ik it's fake but like ocd is not a disorder of logic
