Just to chime in here on BPD as well (for source, see comment above - I spent a couple of years fairly immersed in BPD literature as my wife was studying it pretty intensely for school/work, and I also had a personal interest as a result of some family members who had been diagnosed): fiatchamp's right: that description of people with BPD is waaaay off the mark, and for what it's worth is a prime example of the stigma against BPD sufferers within the psych community. The best research on BPD (see generally the work of Marsha Linehan and subsequent) indicates that far from being "without feelings", people with BPD suffer from an over-intensity of feeling. It's often compared to being without emotional skin -- just as a person who just had their skin badly damaged will experience extreme sensitivity there, people with BPD are abnormally sensitive to emotional pain -- and end up engaging in self-harm not, generally, as a way to seek attention or manipulate others, but rather to distract themselves from the inner turmoil. It's a rough disease, made worse by pervasive condemnation from most of society, including many in psych. Thanks again for your work on the suicide line -- and if still you're interested in the topic, please read up on the post-1990s research on BPD. It will be worth it.
