Good question, bluebicycle!
As for depression, yes, I knew, and did identify it as depression, at least in the really major ones. The first of which was at 20, complete with sui ideation. I had no idea WHY it was happening, but DID recognize that there was no mistaking it with being sad.
For hypo, no, no idea at all, because I didn't know about BP. I certainly knew I could (for instance) make some rather inexplicible sudden major decisions, and even that this was problematic. But I never questioned anything
when it was happening, lol! "Questioning" something???! What's THAT?! "Move along, folks! There's nothing to identify here!"
With the dysphoric stuff, I was painfully aware of when it was happening, but always "identified" it as major character weakness. If I could just pull it together, it'd go away, right? Sigh.
