What is Borderline Personality Disorder (BPD)?
A borderline writes:
"Being a borderline feels like eternal hell. Nothing less. Pain, anger, confusion, hurt, never knowing how I'm gonna feel from one minute to the next. Hurting because I hurt those who I love.
Feeling misunderstood. Analyzing everything. Nothing gives me pleasure. Once in a great while I will get "too happy" and then anxious because of that. Then I self-medicate with alcohol. Then I
physically hurt myself. Then I feel guilty because of that. Shame. Wanting to die but not being able to kill myself because I'd feel too much guilt for those I'd hurt, and then feeling angry
about that so I cut myself or O.D. to make all the feelings go away. Stress!"
Therapists use a book called "Diagnostic and Statistical Manual" (DSM) to make mental health diagnoses. They've outlined nine traits that borderlines seem to have in common; the presence of five or more of them may indicate BPD.
However, please note the following:
DSM-IV Definition of BPD
Following is a definition of splitting from the book I Hate You, Don't Leave Me by Jerry Kreisman, M.D. From page 10:
The world of a BP, like that of a child, is split into heroes and villains. A child emotionally, the BP cannot tolerate human inconsistencies and ambiguities; he cannot reconcile anther is good and bad qualities into a constant coherent understanding of another person. At any particular moment, one is either Good or EVIL. There is no in-between; no gray area....people are idolized one day; totally devalued and dismissed the next.
Normal people are ambivalent and can experience two contradictory states atone time; BPs shift back and forth, entirely unaware of one feeling state while in the other.
When the idealized person finally disappoints (as we all do, sooner or later) the borderline must drastically restructure his one-dimensional conceptionalization. Either the idol is banished to the dungeon, or the borderline banishes himself in other to preserve the all-good image of the other person.
Splitting is intended to shield the BP from a barrage of contradictory feelings and images and from the anxiety of trying to reconcile those images. But splitting often achieves the opposite effect. The frays in the BP's personality become rips, and the sense of his own identity and the identity of others shifts even more dramatically and frequently.
Dissociation is the state in which, on some level or another, one becomes somewhat removed from "reality," whether this be daydreaming, performing actions without being fully connected to their performance ("running on automatic"), or other, more disconnected actions. It is the opposite of "association" and involves the lack of association, usually of one's identity, with the rest of the world.
There is no "pure" BPD; it coexists with other illnesses. These are the most common. BPD may coexist with:

The primary reason that some experts have proposed that BPD and bipolar disorder may be related is that they share the common feature of mood instability. Bipolar disorder is associated with mood shifts from depression to mania (a mood characterized by elation, decreased need for sleep, and an increase in activity) or hypomania (which is similar to mania but less severe). BPD is also associated with mood changes (sometimes called "emotion dysregulation" or affective instability). People with BPD can frequently change from feeling fine to feeling extremely distressed in a matter of minutes. Impulsive behavior is also frequently experienced both by people with bipolar disorder and by people with BPD.
What is the difference between BPD and bipolar disorder, then? Some major components separate the two. While the disorders are both characterized by mood changes, the quality of the mood changes can be very different. In BPD, mood changes are often more short-lived -- they may last for a few hours at a time. In contrast, mood changes in bipolar disorder tend to last for days or even weeks. Also, mood shifts in BPD are usually in reaction to an environmental stressor (such as an argument with a loved one), whereas mood shifts in bipolar disorder may occur out-of-the-blue. Finally, the mood shifts typical of BPD rarely involve elation -- usually the shift is from feeling upset to feeling "OK," not from feeling bad to feeling a high or elevated mood, which is more typical of bipolar disorder.
Although it is not yet clear-cut, research has not found a strong relationship between BPD and bipolar disorder. There is some evidence that people with BPD are diagnosed with bipolar disorder at higher rates than individuals with other personality disorders. One study found that about 20% of individuals with BPD are also diagnosed with bipolar disorder, whereas only about 10% of people with with other personality disorders are also diagnosed with bipolar disorder. This could mean there is some relationship between BPD and bipolar, but it could also be attributed to imprecision in diagnosis, or in the individuals making the diagnosis.
So far, there is not enough research to suggest that BPD and bipolar disorder are related. Although there are definitely some shared features,
there are also some marked differences between BPD and bipolar disorder. Also, the co-occurrence of BPD and bipolar disorder is not large enough to suggest that the two disorders are related.
However, more research is needed on this topic. It may be that future research, for example on the genetic and biological causes of BPD and bipolar disorder, may reveal some undiscovered
elationships between the two conditions.
