PS - I wanted to add that I have already seen that a number of people with BPD have already written books based on their own experience of having it, and those books are available through Amazon. I have not personally read any of them, so I don't know if they cover the particular "subset" of BPD sufferers that I want to focus on. But I have read little-to-nothing in the professional mental health field that focuses on this subset. The very small amount I've read that DOES mention it refers to this subset as "The Quiet Borderline" or the "Acting-In Borderline."
