I remember back when your signature line was along the lines of "If I ever want off my meds or out of therapy, somebody please kick me". Well.....let's just say you were doing a lot better then, and for a lot longer. For months now your posts have concerned me, as well as a number of other members, and I think maybe it's time to realize that when multiple people are telling you the same things, you would do well to listen.

I've questioned my diagnosis too. (Haven't we all?) In fact, last fall I pretty much had myself convinced I wasn't bipolar at all, that I was merely going through an existential crisis and had finally snapped out of it. (This was in the middle of a particularly severe and persistent manic episode.)

So I asked my family and friends what they thought of my theory, and they all said I was full of $#!+. Then I brought it up to my pdoc and he started talking hospitalization. That was after HE told me I was full of $#!+. I guess I was pretty far out there, I don't really remember a whole lot about that time, but I do recall that once he put me on a 2nd AP, I came back to earth. Then the depression hit, and that forever dispelled any illusions about NOT being bipolar.

I suspect you haven't had that come-to-Jesus moment yet, even in the face of overwhelming evidence that you indeed are BP and need consistent treatment.
I know your eating disorder complicates matters, but there are APs out there that are weight-neutral. I'm a nurse, not a doctor, but I agree with your T that you are under-medicated for the severity of your symptoms.
