We don’t know for sure if Eric had BPD. We don’t have any clue about his diagnosis other than that it is likely to be in the spectrum of anxiety and depression – and that particular spectrum is a huge field with a lot of conditions attached to it that can and do interplay with one another, complicate each other if they coexist, and express in very different ways. (And the only reason why I’m willing to make an educated guess about that spectrum at all is because both of the medications he was prescribed are commonly used to treat that particular spectrum.)
We cannot and must not assume he had one disorder or the other. We can call some diagnoses more likely than others, sure, but we do not possess enough information to be that definite about it. If other people want to push one particular diagnosis over the other, that’s their decision. Factually speaking, I cannot support that course of action in the space of my own blog.
BPD is hallmarked by quite a few things, but nothing you described just now remotely fits into its most-known patterns. Aside from the fact that we don’t know Wayne well enough, the way in which the Harrises elected to parent their children is not immediately connectable to one diagnosis or the other. It’s true that a fair few conditions can be passed down within a family from parent to child, but we cannot assume that this was the case in this family.
