It's always something I have to think about. This sounds, however, like a judgement of "good or bad". Sounds like what therapists used to be supposed to think about borderline personality disorder, that "those" people "are" impossible -- rather than admitting that the professionals have a lot of trouble dealing with them using the same techniques that they are used to using. So when I encounter something like this, it frightens me, because I can see it being used to cover up the fears of the one who makes the judgement, not admitting that's what's happening, and confusing the whole lot, and driving me into more panic.

Even if this is not the intent, I do not see people making an effort to be clear, and distinguish what they mean from how it could be interpreted. Just as an example, using the word "impossible" to describe patients. I have a book whose title is Therapy with "Impossible" Patients -- so the people who wrote it recognized that that term has been used by some "professionals" -- and that it claims to describe a "reality" but in fact does not.

What if it is found to be true that I fit into the category of someone with "certain personality disorders that find critic with therapists, they spend their life finding whats wrong and not whats helpful to avoid becoming vunrable enought and accepting perhaps someone else may know something we don't."? Then what? Does this mean it is OK to consign me to outer darkness, to exile, to the leper colony? That is how it is used sometimes. It is what frightens me.

Has this kind of thing been used against me in the past? Yes.
