If you want a good litmus test to give you a warning sign on potential personality disorders lurking beneath, listen carefully (over time) for these two highly-used adverbs: always and never. Do you hear them a lot? Do you notice that, while we all use them from time to time (notice my slip?), most people tend to catch themselves and correct for such extreme comparisons. Not so with the BPD. The use of these adverbs is proficient and often. I’ve lost track of how many times I was told that I ALWAYS do this or I NEVER do that…and the risk is that you eventually believe them. This sort of extreme thinking is a classic sign of a personality disorder….so maybe we should listen a little more carefully and watch out for those adverbs!
