Type one or two? That's how I was misdiagnosed as bipolar-II. I have unipolar depression, but the high dosage of amphetamines I was on had me tweaking apparently. Once my dosage was drastically reduced, I had no issues other than normal depression ever again.
You would think taking me off the medication/reducing the dosage would have been the first step in diagnosing such a condition, but we're talking about the two most pseudoscientific fields of science/medicine, so perhaps I was wrong to trust them.
