Self-loathing theme is quite an ubiquitous mind infestation. I have not been diagnosed with BPD, but I hate myself regardless. I have not even realized till recently that the way I feel about myself is nothing less of self-loathing, and that is why I can't do things I say I want to do, and will destroy any little gain I may have. I just hate myself. I lost some weight on my recent trip, came back and started gorging myself, till I was back to my disgusting obese body. Then I stopped: goal accomplished. And I could now hate myself not only for being fat but for having no self control. Heck I hate myself for hating myself.

I suspect it is not so much a symptom of, but a cause of a disorder. I don't believe it will go away when we take some pills. It is not merely a dark mood, but a fundational belief about world and self. It'd be like hoping that taking this or that pill would cure us of religion, or of atheism.

But I am not saying it is hopeless. It is not a belief based on truth, and if we really understand the thousands of lies we believe that add up to this self-loathing are just lies it's grip on us may lessen, and eventually be dissolved. Or maybe one day when we hate ourself so much our mind implodes we will see through the big LIE and be free (yup, it did happened to people!)

What I find is helping me with these issues is research: reading psychology books, journaling, and also listening to various motivational, self-improvement people like Wayne Dyer, Eckhart Tolle, Bashar, Byron Katie, Caroline Myss.
