Yeah, she had just broken up with her boyfriend and found a bunch of "self-help" youtube videos that basically just said everyone who disagrees with you is a narcissist, then the algorithm started recommending her videos that said everyone who disagrees with you is actually an "energy vampire" literally and maliciously draining you of your life force. From there she got into all the crazy health conspiracies - which of course happened right as she was diagnosed with DCIS, which is easily treatable, but if left untreated becomes breast cancer. She dove head-first into all of the conspiracies after that, throwing money at anyone claiming to cure cancer so long as the method wasn't backed by "big science," and died of breast cancer a few years later.
