A very useful article:

This guest blog is from blogger Paddy Vipond (To Psychology Today). His blog Rambling Thoughts (which, as the title suggests, is not just about BPD) is at http://troubleandsqueak.wordpress.com/. Please keep in mind that like in all my guest posts, these are his opinions and may or may not reflect on my own. I like to publish a variety of views.

On behest of my girlfriend of nine months, I am writing about what it is like to be with someone who has Borderline Personality Disorder (BPD). It is a complicated mental condition that is thought to affect as many as one in seven of us, according to the book New Hope For People With Borderline Personality Disorder.

Although I have read books and researched BPD, I cannot even come close to imagining the mental anguish that my girlfriend must have suffered and be suffering. Its entirely alien to me and most people.

My borderline girlfriend just came home. I read this to her and we both cried.
