Hi there,
The pwBPD in my life used to claim that she suffered from all sorts of abuse, bullying and traumas. At first, I gave her the benefit of the doubt. But over time, I learned that her version of events was generally distorted. The fact patterns usually didn't line up. Most of the time she would omit important details, such as her role in starting a fight or threatening violence. Sometimes she would use projection; she would accuse others of "assaulting" her, when what really happened is that her parent called emergency services when she threatened self-harm. Other times, she would be vague about the purported abuses, to keep people guessing. But one thing was constant: she always portrayed herself as a victim. According to her, she was abused and bullied by everyone close to her, from siblings and parents to extended family, from roommates and workmates to ex-friends and romantic partners. I think she experienced life as traumatic, and she was basically "primed" for a fight or flight response, even in ordinary situations. Does that ring true in your daughter's case?
Here's my take. PwBPD can have emotions that constantly feel overwhelming, and their default attitude is negative. In addition, they are prone to over-the-top, often inappropriate outbursts and impulsive reactions with other people. I think they feel deep shame for their behavior and choices in life. But rather than take responsibility, apologize and move forward, they have a maladaptive coping mechanism, which is to blame others. A typical way of blaming others is to claim abuse, even when there is none. I think pwBPD will ruminate about negative social interactions so much that their brain will invent malicious intent and exaggerate harm. She can spend weeks in this negative thinking loop. She ruminates so much that her very identity becomes one of a victim. If you challenge her, you're not just challenging facts, but her very identity. Because if she's not the poor little abused girl, then who is she?
On these boards there's a lot of talk about validating feelings, and there are some scripts about what to say, such as "It must be terrible to feel you were treated that way." You will be advised not to validate the invalid, and not to confess to something you didn't do, which is sound advice. But here's the thing that I've experienced with the pwBPD in my life. After "indulging" in her victim narrative through validation of feelings, I don't think that did her much good. By validating her victim narrative, I think it encouraged her to dwell on it even more, and she got "stuck" constantly ruminating about negative thoughts. The worse she got, the farther back in childhood she'd go to dredge up stories of supposed abuses. It was clear to me that when the pwBPD in my life was "stuck" thinking about negative past events, she did not do well. Conversely, when she talked about the present and future, it was a clear sign that she was doing much better.
I guess I'll wrap up by saying that you might be able to tell what's bugging your daughter by listening to her claims, reading between the lines so to speak. If she says that other people are berating or disrespecting her, that could mean she feels inferior/insecure/childish. (I frequently hear similar complaints from the pwBPD in my life, who feels very insecure about being "behind" her peers in school/life.) If she says people are violent towards her, that could be projection about her wanting to inflict violence or self-harm. In the context of a romantic relationship, if she's accusing her partner of infidelity for no reason, that could mean she's insecure in the relationship or thinking about infidelity herself.
