I hope your wife has a good outcome for her outpatient surgery tomorrow, jedimaster. All my best to her... .It does sound promising that she did the legwork needed for it to be taken care of, and even the realization that some of the farm animals need to be sold. Congratulations
My own adult (37) son who was diagnosed with BPD in April 2013 has never seen a Neurologist, but is being treated by a Neurofeedback Therapist. He started in mid-April 2013, and is still having Neurofeedback sessions at this time, and it has helped him
immensely. In fact, not only is he in remission for his BPD (I really doubt he would be diagnosed with it at this point; almost all of his BPD symptoms and behaviors have pretty much disappeared--all except his Social Anxiety, which is a lot better at this time), but he is now almost 20 months clean and sober from a multi-year Heroin Addiction, also.
I do believe that the Neurofeedback is what has made the difference for him since 2 "regular" Rehabs didn't help him at all; he relapsed within 6 months of completing each of them, until being discharged from the Dual Diagnosis Program that diagnosed his BPD, and then having this regular, continuing Neurofeedback Therapy. Both programs have been life savers for him

I know your wife doesn't have a Substance Abuse problem, but the Neurofeedback is good for all types of symptoms and behaviors and disorders. I don't suppose she would consider such a thing, or if you have a Neurofeedback Therapist near to you? Just a thought... .She's done brain scans for him and works on all the parts of his brain that are involved with BPD and all of his symptoms and troubles.
I wish her Godspeed tomorrow, and all my best for you and your family... .
