I don't think there is a cure. I wish there was!

I view my illnesses a lot like Diabetes, or Asthma, or some other chronic illness. It doesn't go away, you're born with it, you'll die with it. But it can be managed well. A diabetic can eat chocolate cake and not give a dang about their sugars, or they can test regularly and eat a balanced diet. Just as a Borderline can try to go it alone and never get therapy, or they can see a therapist and possibly take meds and do what they can to manage their condition.

So basically, I think it can be well-controlled....but not cured.
