I always hear about emo guys and girls who cut themselves. So, I was just kinda wondering if they have borderline personality disorder. Do they?

Some may, but personality disorders can't be diagnosed until adulthood and most people have outgrown being "emo" by then. Not all people who cut have borderlineand not all people who have borderline cut; it just happens to be a possible symptom.

I don't think cutting and borderline personality disorder go together. Borderline personality disorder is a lack of affiliation with a particular group, and/or associating oneself with every group. So the fact that a emo kid finds him or herself to be emo negates the possibility that they are borderline personality.

Not necessarily. Cutting is nothing more than a coping mechanism for overwhelming and/or disturbing emotions that the person hasn't learned how to appropriately handle. There are healthier ways to do so, obviously, but that's all it really is. I don't know all the specifics for BPD, but it is MUCH more complicated than the assumption that if one cuts they are BPD.

DO BOILING EGGS STINK????

UM NOT NECESSARILY!! >_<

Potentially, just as any other group of people may.

Symptoms:
While a person with depression or bipolar disorder typically endures the same mood for weeks, a person with BPD may experience intense bouts of anger, depression, and anxiety that may last only hours, or at most a day.5 These may be associated with episodes of impulsive aggression, self-injury, and drug or alcohol abuse. Distortions in cognition and sense of self can lead to frequent changes in long-term goals, career plans, jobs, friendships, gender identity, and values. Sometimes people with BPD view themselves as fundamentally bad, or unworthy. They may feel unfairly misunderstood or mistreated, bored, empty, and have little idea who they are. Such symptoms are most acute when people with BPD feel isolated and lacking in social support, and may result in frantic efforts to avoid being alone.

People with BPD often have highly unstable patterns of social relationships. While they can develop intense but stormy attachments, their attitudes towards family, friends, and loved ones may suddenly shift from idealization (great admiration and love) to devaluation (intense anger and dislike). Thus, they may form an immediate attachment and idealize the other person, but when a slight separation or conflict occurs, they switch unexpectedly to the other extreme and angrily accuse the other person of not caring for them at all. Even with family members, individuals with BPD are highly sensitive to rejection, reacting with anger and distress to such mild separations as a vacation, a business trip, or a sudden change in plans. These fears of abandonment seem to be related to difficulties feeling emotionally connected to important persons when they are physically absent, leaving the individual with BPD feeling lost and perhaps worthless. Suicide threats and attempts may occur along with anger at perceived abandonment and disappointments.

People with BPD exhibit other impulsive behaviors, such as excessive spending, binge eating and risky sex. BPD often occurs together with other psychiatric problems, particularly bipolar disorder, depression, anxiety disorders, substance abuse, and other personality disorders.
