I didn't think that was likely, but a Mayo Clinic newsletter I got today says it can be treated via psychotherapy, sometimes supplemented with drugs. It is a long process (months or years) but it can teach the person to cope with the condition and function better in relationship.
I like this advice: "Don't blame yourself for the disorder, but recognize your responsibility to get it treated."
I'd never heard of the disorder before I joined here, where some people are coping with parents with this disease.
Do you know someone who is coping better with BPD through treatment?
