Hi BeagleDad1,
I'm glad that you have returned to this board. Your first message of last year didn't say much. But the fact that she has been diagnosed is very good. It even helps her to feel less worthless, because she knows it's a disorder and the disorder is treatable. What she doesn't have is the desire to face the facts in her therapy. It's ok to switch therapists a few times, but if she wanted to really heal, she would do that until she found one that she feels safe with.
One red flag that I see in your post is that you try to be "the lighthouse keeper." It sounds like you are making it easier for her to fail in many ways, are you? But if you do that, you make yourself an enabler, and things get worse. Because what will motivate her to change is the overseeing of the possible future consequences of her disorder. But with you always covering up for her failures, she will not feel like her disorder is a threat to her.
For instance, as a consequence of my wife's disorder, I have forced us to live apart, with no guarantees. That has helped in motivating her. However, since I'm still there for her all the time, she doesn't quite fear further consequences. But I'm sure that if I stop doing this, she will get herself moving faster (toward treatments). I'm afraid that this will only happen when I get tired, give up, and move on.
In regard to the pains, this may be because of low endogenous opioids (the natural pain reliever of our body). A German study of 2010 proposed that this is a key feature of BPD (

My wife is trying a drug used to treat opioid addiction and also alcoholism, and which has also been used off-label to treat BPD symptoms with success in almost all studies. Though since my wife is not suicidal nor dissociating, we chose to use the super low dosage, which has not been tested to treat BPD but is effective in treating chronic pain otherwise specified and autoimmune disorders.
