For what it's worth, I am creative (or at least I like to think so), and I still often feel like a fraud and wonder whether I really need all these meds and everything else. I think many bipolar people struggle with that. For some reason my memories of depressive and manic episodes seem to fade very quickly, so pretty soon afterwards I start to think it can't have been all that bad and I must be exaggerating. I remind myself of external evidence, like family history, what my therapist says, things that happened during episodes, and so on. As an unrelated point, the ideas I have while (hypo)manic aren't necessarily always my best, although I certainly think so at the time.
