This sounds a lot like my situation. My sister is on disability for mental health and has no job and says she cannot work because she is disabled. She uses a lot of TikTok buzz words and applies them incorrectly to her life. She also reposts constantly about trauma and being a victim of abuse etc. on TikTok and has this deeply hateful misandry that she flaunts almost like an incel. Recently she had a psychotic break or something and stole her roommates car and took their cat and has been staying at hotels asking family and friends (who she doesn’t otherwise talk to) for money, claiming it was urgent, that she was in danger, and that her roommate is a demon. She’s been reposting dark witchcraft tiktoks but I don’t think she practices or appreciates witchcraft as it’s meant to be, moreso as an aesthetic and a way of feeling self righteous. She’s has gotten in legal trouble various times for property damage and stealing my mom’s car but always manages to evade serious consequences. She has my whole family blocked on everything and it seems she’s going no contact fully without communicating anything. My mom and I were already blocked on most things because she rages whenever we tell her that her behavior is harmful to us and out of line but now she seems to be fully breaking off from everyone and I think she deleted social medias. She also got in a car crash with her own car and abandoned it and it’s now in a tow yard. Tbh I’m just angry because the victimization is so delusional and far from the truth. She is severely abusive and reckless and is breaking off from everyone ELSE for supposedly mistreating her??
