Hi, I'm a former borderline and wanted to encourage people that BPD (Borderline Personality Disorder) can be cured and/or greatly improved by good treatment.

I found some interesting research that is quite encouraging. Here is one study:

The results of the 88 patients in this study were quite encouraging; many of them recovered to the point of no longer being diagnosable as borderline, and they had quite severe histories to start with.
There is also this longitudinal study -

It shows that even without treatment, many borderlines improve a lot.

Lastly here is an article I wrote discussing these data in detail -
