Personality disorders are very hard to treat. There is no effective medication for BPD. It's not like Bipolar disorder where you can take your meds and be normal.

I asked my doctor once, "Will this ever go away?" He replied that I would always have interpersonal problems because of my borderline personality traits but that by learning the skills, I can manage it.

Just going to therapy doesn't necessarily help. We have to take an active role in our recovery, by doing homework, practicing the skills, etc.
