Many people in our lives exhibit traits of this disorder, but it is important to know how to deal with them and to try to manage their illness. The effects of it can be far reaching as these individuals not only disrupt classrooms, but will try to destroy others around them when things don't go their way, whether it is through attacking the instructor, the institution, fellow classmates, and even themselves. As you read through the characteristics, I am sure you will recognize individuals in your workplace / classroom who have BPD.
I've included a link from Psychology today which describes the disorder a little more clearly with examples. http://www.psychologytoday.com/blog/stop-walking-eggshells/201111/blame-storms-and-rage-attacks-common-borderlines-narcissists
And another on how to better deal with these individuals in the classroom, by not allowing yourself to be manipulated: http://www.borderlinepersonalitytreatment.com/borderline-personality-disorder-manipulation.html
