SOO my question is( I think I know the answer) does the BPD ever get it? Is there ever a long term noticeable change in them?
BPD isn't about "getting it" - most pwBPD are very intelligent. It is an emotional issue that needs treatment teaching skills on dealing with over-active emotions. Over time with proper therapy, the BPD behaviors can be diluted or gone away. The brain neurons for the maladaptive coping skills a literally rewired.
Again, it has nothing to do with "getting it". It is like reading a bunch of books on diet and exercise, yet being over-weight because you never practice the tools with a trainer or nutritionist.
