Hey Under*Over, I know what you mean. Though I don't know that I'd call myself high -functioning (I can only handle a virtually no stress part time job with no phones or public interaction), I've been doing well BP-wise (though another dx not well) for awhile now and I like to think I'm... not cured obviously, but kinda "normal", whatever *that* means.
It'd be really easy to over-extend myself right now. I KNOW that doing well can be attributed to meds and work on my part (better sleep hygiene for instance), but yeah, I know at any minute it could all go to ****. And yet am I tempted to tweak the meds? Yup.
(I might make a thread about why, but even without that reason I'd be tempted to think maybe I don't need them(!!!!))
Anyhow, yes, doing alright and it's kinda weird. I can SO relate to your post #6. Instead of feeling odd or bad or like you have no right to complain when doing well, maybe reframe that to think about that you are in a place where you are able to give back (I know I have a hard time feeling useful when I'm doing badly).
Take when we need, give when we can -- it's what makes the forums go 'round.

And that doesn't mean no "complaining" (which you aren't), because even when doing well we can have challenges to deal with.
So it's all good as they say. Glad you are doing well. Hooray!
