I took the test and my score was 13 which means having a BPD is unlikely for me. Though my feelings after the break up were intense, and I still feel very low for ending the relationship, I did not relate to most of the stuff in the test like;

"Feeling of emptiness" - I don't feel empty. I usually feel something, I can hardly say it's emptiness.
I never found myself being paranoid, I am more or less naive when it comes to the intentions of others I think.
I am too perfectionist to idealize people too, I see many faults in many people, it makes it hard to open up and to be warm in a relationship. This is the reason why the other thing about intense relationships can't be true too... I also don't want to make myself look a fool in a romantic relationship so I hold back as much as I can even after a longer time. And... The thing about the unstable ego image... just no... I haven't changed my opinion of myself in many many years and I've been following the same goals since elementary school really...so ... no

I do have intense emotions... which might seems borderline...but as far as I know, I do not show much of other symptoms... I am just hypersenstive, but also in very introverted and reserved manner...I don't show much of what I feel out of the fear of being seen as stupid or too emotional, so I usually play it really cold and cool.
