She does. After an abusive encounter with her parents in 2020 she went to see a psychiatrist and got diagnosed. She had a twitlonger talking about it, and for a time had BPD in her profile. She's quite internet savvy, though, so she probably saw having her BPD diagnosis front and center as a potential target to attack her with and removed it.Nah bro, do you know anyone with BPD in real life? They can be quite a handful. I can't imagine working with one to be easy, especially in an unsupportive environment like Nijisanji.
(I'm assuming that she does have borderline disorder and that's it's not just a rrat)
Here's aselection of symptoms from this page:
> A pattern of unstable, intense relationships, such as believing someone is perfect one moment and then suddenly believing the person doesn't care enough or is cruel.
> Periods of stress-related paranoia and loss of contact with reality
> Inappropriate, strong anger, such as losing your temper often, being sarcastic or bitter
I wouldn't be surprised if her Manic need to constantly be working and doing projects is part of how she keeps herself stable, but that mania ends up being difficult to work with.
