BPD is characterized by black-and-white thinking and things like that. Extremes. Love hate.

Your posts are always so well-reasoned, balanced, this and that, well aware of the nuances and very perceptive... a lot of self-reflection...yes, with a good helping of self-doubt, but no extremes.

So I would totally agree with the judgment of every professional you had seen before you started seeing this T, in that you clearly do not have BPD.
