I can't shed light on your Dx except it sounds like BP 1 to me, although that's a guess. And like others have said what label you "have" isn't as important as effective treatment, although pinning down an accurate one might aid in that.

My whole life I've felt mostly either "less than" or "better than". More on the less than side.
No middle ground for me. It's the way I have lived too, which can get chaotic.

Real or not I have always love fairies, and most things magical.
And I'm not young.

I hope you're doing ok. Oh! One more thing - out of unplanned and stressful things, often much good has come from it - more than I could have created.

Not much wisdom imparted there but I hope you're doing good.
