I'm someone who's been recently diagnosed and did a bunch of stereotypically bad things. Getting the cops called on you, substance abuse, rage, have physically hit people, etc. 

Being diagnosed with BPD (and other things) gave me some deep comfort and a lot of mixed feelings about having a personality disorder, but I always feel deep mixed feelings about the 'gifts' of BPD. I don't see it as something that should be stigmatized against but I don't see it as something that should be romanticized either. 

I often see the capacity of feeling deeper, connecting with others easily, having more empathy (I personally don't really agree with that) as common BPD 'upsides' but I don't agree with using these things as a positive uplift for having BPD. Any more than having symptoms of PTSD. And whatever upsides there are to being borderline are offset by some very nasty things.

I think it is good to have a more positive approach to having BPD and coping with it, but I don't think trying to highlight and look for things that are 'good' about it to be a healthy approach. It's a very destructive ugly disorder that shouldn't be stigmatized. But just because it shouldn't have a stigma to it, doesn't mean it's something to make into a positive thing or to soften.
