I wanted to post this in case it even helps one person. 

BPD as most know is the result of childhood trauma (if you think its genetics, get a new doctor; all the evidence for genetics is completely confounded). 

The truly best treatment to replace what you didn't get in life... is to well get some version of it, while accepting the loss. 

Therapy helps... BUT, more and better therapy is, well, better. Consider contemporary psychoanalysis.

Psychoanalysis is usually multiple days a week. Contemporary psychoanalysis is not Freud, it's led with compassion and love, not cold analytics. 

If you truly want to experience the world differently; and are willing to work for it. Find a renowned psychoanalysis in your area and see if they have openings. We're not talking cbt bullshit. were talking many many sessions over years. Investment. commitment. responsibility. It can change your life. 

I know this is expensive, and that's my main problem with even advertising this treatment. But if anyone can afford it, and anyone is motivated enough, if someone really wants to experience what they crave so deep down below the emptiness. This is the best you can get, and it works. and lesser therapists will disparage it, but they don't know the truth or even how to read journals correctly.

Get your needs met. 

Not here to debate, just maybe help someone.
