I'm not a doctor or anything... but W pretty explicitly chronicled her thought processes in this journal over a long period of time. Just from the journal I've identified 7 of the 9 criteria for BPD, and she only needs to meet 5 to be diagnosed.
Thankfully I educated myself early on, and my first evidence bomb was a pretty good wake up call for W's attorney.
Soon I'm going to drop my second, and I'm reminded of Kevin Spacey's quote from Se7en:
"Wanting people to listen, you can't just tap them on the shoulder anymore. You have to hit them with a sledgehammer, and then you'll notice you've got their strict attention."
"You can't reason someone out of a position they didn't reason themselves into."
