I don’t generally like the sort of comparisons I see so often that stigmatize BPD as a less stable, “crazier” form of NPD, but it’s a fact that people with both disorders have problems with rage, and their rage can manifest in very similar ways, even though the motives behind the rage are different.
Here’s an article from Narcissist’s Wife that talks about the similarities and differences, and how you can protect yourself from the angry B’s. (sorry for the bad pun, I couldn’t resist).
Borderline Personality Disorder has many symptoms in common with Narcissism. In fact, the two disorders often overlap to some extent. This can cause a lot of confusion for the spouses and partners of these people as they go from seemingly normal and ok and you start thinking “well, maybe they aren’t a narc, maybe they were just having ________” (Insert whatever excuse you happen to go to when they’re behaving badly). Not everyone is 100% psychopathic Narcissist with the heart of a snake. As with anything in life, sometimes Narcissism comes in shades of grey.
All that said, Borderline Personality Disorder can express itself in ways very similar to Narcissism and one of the most common is in rage. The temper tantrums narcissists throw are very similar to a Borderline, though they are motivated by different things. Knowing these things may help you not only anticipate an explosion, but temper it as well.
Unlike a Stone Cold Narcissist (who uses rages to manipulate, control, and assert his superiority) borderlines are extremely insecure and emotionally unstable. Nearly all their emotions go up and down (leading one to question Bipolar disorder) but anger is the most difficult for those around him/her to put up with. Their intense and fiery anger comes from a deep belief that you don’t care about them, are not listening to them or are otherwise not meeting their needs. They strike out in pain to punish the one who they believe is hurting them. Unfortunately, this may all be in their heads, and their pain could actually be coming from another source that they are not prepared to deal with or that they are otherwise bound to not be able to express anger at, so you become their emotional punching bag.
Those without an overlapping Narcissistic disorder may feel shame and embarrassment, and apologize when their emotions have calmed down a bit, for fear of losing you. Though they may feel remorse, their behavior will not get better unless they are in treatment. A Borderline with Narcissism though, will not make such overtures. Your perceived faults are deserving of their rage in their eyes and the punishment for your shortcomings in their eyes is their scorn and anger. They are more demeaning in their anger, and can be much more passive aggressive.
