I personally don't like the label of "bordeline."
It's not just getting people to understand, I think, but often the amount of patience to go along with that knowledge is absent. There doesn't seem to be a definitive definition and thus the label, and that makes healing and personal understanding by the patient difficult to begin with.
I don't think it's "just" those with this label, but with people in general, mental unwellness or not. Many people today are so involved in their own lives, in themselves, that they just don't have the time or energy for high maintenance others.
Don't take it personally, it's their issue.
