I used to be a high-functioning BPD most of the time, then I had two breakdowns and by the end of the second one I found out I had BPD and started DBT. This was about 6 months ago and while I did not realize it at first, now I'm convinced everything DBT teaches us is just be high-functioning which I know how to do anyway, so what's the relief in this?

High-functioning was the reason I broke down, I simply cannot regulate myself for so long and not break down. If I follow the DBT routine, I'm afraid I'll just break down again. Maybe not as fast, but but it's pretty much impending.
