What’s borderline personality disorder? My gf was just diagnosed. Is it serious?
If your girlfriend was diagnosed by a mental health professional, and not just by someone who looked something up on the internet, then you both have a problem. In mental health circles borderline personality patients are known as "therapist killers," not that they actually kill anyone, but they wear the therapists out. The hallmark of the disorder for the person involved with a borderline is that one day you are the best thing in the whole world and the next day you are the scum of the earth with no logical explanation for either one. Even for an experienced therapist, it makes you want to go jump off a roof. So, yes, it's serious. On the good side if she is working with an experienced therapist who specializes in personality disorders, she can make good progress. You may need professional help of your own.
