Borderline Personality Disorder

I have never been diagnosed with Borderline Personality Disorder but my own PTSD symptoms sometimes inflame and appear a bit close to this diagnosis but then it all subsides again. Anyhow, I found this article interesting as I do have problem with rage but infrequently and rarely - and I do feel about two years old when I am in rage mode. I know that it links to the abandonments I experienced as a child by my parents and it is helpful to read the guidance here.
