Cognitive functioning disorder? What is your diagnosis? Bipolar illness is a mood disorder,
not an intellectual one.

Nobody's perfect; try to remember that. As for mistakes, we all make them and plenty
of them at times. Don't see yourself as a cognitive dysfunctional person, please.

If your medications aren't helping to control your moods 60% of the time, talk to your
doctor about tweaking them or changing them. Mood stability is what you're aiming
for. If we don't have that I can see that it might distort intellectual functioning, but
medications are designed to help stabilize emotions.
