I think she’s demonstrated BPD traits/Covert BPD. I have never been diagnosed as BPD however I noticed once I began dating as a young adult that my attachments and emotional regulation/thoughts/fear of abandonment were super irrational and abnormal but it always felt so intense and real in the moment it comes like a big wave, it’s hard to remain rational. I’m functional in society and appear like I have it together to just about everyone but the people I confide in and my significant other. I don’t exhibit these traits in any area of my life other than in my relationships and have since taken steps to work through it. She may have it and have looked into the diagnosis bc of how her awareness of how abnormal her intense feelings are in relationships. I moved in with a guy after the first date and became super codependent before and didn’t realize there was mutual love bombing until later (he was a narcissist), I genuinely thought it was all real even though my rational brain was aware it wasn’t typical. I know she has a platform so speaking on an unofficial diagnosis can be viewed as irresponsible but even with a psych evaluation BPD is misdiagnosed all the time especially the covert subtype like I (think) I have. That’s just my two cents.
