My sister posted a TikTok storytime laughing about how I froze up and walked out on a hookup last week. People from our campus are in the comments and I feel completely sick. How do I get her to delete it immediately without turning it into a massive family war?

Tell her bluntly to take it down right now, without debating the details or letting her turn it into an argument about whether it was 'just a joke.' Your freeze response was a real, vulnerable moment, not content for her algorithm. Send her a single, firm message: 'Take that video down immediately. You put my private life and an uncomfortable sexual experience online for strangers, and it is humiliating. I am not negotiating this.' Don't apologize, don't explain why freezing happens, and don't involve your parents yet. If she resists or leaves it up for views, report the video directly to TikTok under privacy violation or harassment—platforms usually remove content depicting non-consensual personal stories quickly if reported by the subject. You didn't cause this conflict by asking for privacy; she caused it by broadcasting yours.
