Kylo, reading through your thread for the first time...I can sympathize with observing traits of BPD. I'm pretty sure my W is somewhere on the spectrum, too. Her aunt (mom's sister) has schizophrenia and I think her mom, had she sought help, would have been diagnosed as clinically depressed. W has has been dealing with depression/panic attacks/extreme anxiety since I've known her.

Has your W shown these other kinds of attributes (depression, etc.)?
