Thank you, powertools!
Unfortunately, the DBT center here is mostly geared toward substance abusers, and doesn't seem to have anything for BPD in English. I have some DBT workbooks, so I am trying to do it on my own a bit while I search for another T/Dr. Most of the English-speaking ones here deal with expats who are having trouble "integrating" and aren't willing to work with borderlines, but that doesn't mean no one will, I just haven't found the right person yet
