well borderline is an old term that don't really fit the description and what he calls it is not really right either cause it dont cover everyone but I understand what he comes from. I can use myself as an example:
I got beat up by my day care sitter before the age of 2, now I don't remember this, but my mom noticed I was depressed and one day caught the woman in the act. I went from a happy kid to yeah..
at age 4 I was raped by a neighbor and friend of the family, at the same time my father who was an alcoholic had started to abuse my mother and tried to kill us both, my mom wanted to commit suicide, and more than once did I see that woman count her pills, and more than once she was trying to kill me first cause she didn't want to leave me with my father. I don't remember all the details anywhere, I have bits and pieces, pictures flying through my head. BUT my body remembers the fear, you know that creeping anxiety? that comes from soemthing that usually happened in your childhood, I was petrified, and to this day I can not for example finish a guy orally, if I do, I panic and starts vomitting, hyperventilate and pass out, usually I wake up in the ER (done it twice) the fear is so overwhelming that I go ballistic.
Seeing scissors sometimes or using them can do the same thing, that one has become way better, but if I have an anx moment I stay away from them. The clearest picture I have in my head was the one where my mom stabbed for me with the scissors I ducked and she missed my face with half an inch and destroyed her purse. She woke up from her insanity that time and called the ambulance on herself but the fear its still there. So it is post traumatic stress in a sence, however due to the feeling of abandonment its more complex than that and can be triggered by so much more. When a parent abandons you you almost take to any method to take care of yourself and to have trust broken by a parent or a closed one make you so paranoid in the end that you all of a sudden have abunch of issues. All these back int he days was clumped together as borderline, now they start to define it more.
I can even relate this to animals, I study behaviorism, and honestly I don't understand why no Dr's or shrinks has seen this pattern before, in dogs there is something called fear imprint stages
http://www.diamondsintheruff.com/Develo ... tages.html , IF soemthing happens that is very scary like physical abuse from a human, or an attack from another dog, hit by a car, thunderstorm that is really bad during certain periods of their ages, the dog will get emotional issues almost PERMANENT in imprinted in their behavior. You can sometimes fix it to a certain degree but the animal never becomes as stable as it was supposed to be. Through counter conditioning you can teach the dog to manage the situation as well as manage the situation around the dog pretty much how we have to relearn to avoid certain negative thinking patterns. But basically what happens is that the deepest form of survival is triggered in them (which make them fear aggressive) which is a description that would fit the borderline as well, through the dogs I have got to known myself and improved myself with the same techniques I use on them. We are fear aggressive, fear of abandonment makes us aggressive towards the people we actually love cause something happened when we were too young to fully grasp and overwhelmed our minds with fight and flight that it basically turned into a new deep instinct.
Same thing with people who get chocked in the war, a broken exhaust pipe that goes makes them loud gun like noises can make them duck cause it has turned into a reflex.
I have to say that your dr's description of it is rather close on what it can be for so many, for me its a spot on descritpion but borderline also covers bigger areas than that.
