Guys, what should I do? Please help. My anxiety just keeps piling up.

There’s this user (@butterfly) who’s been harassing me for the past three days. Whenever I comment on something, she separately mentions me,even when I’m not talking to her,and spreads a bunch of made-up lies that i am a troll blah blah. I honestly don’t know what to do. I’m so tired. I even made a separate comment begging her to stop, but she’s still continuing. And yes, she’s a minor
