Hi Bipolarchic. I hope you are OK. Did your vertigo get addressed?
I think Gabyunbound provided a good reasoning for your bipolar disorder eventually being revealed. However, I totally get that no one wants a doctor or EMT to jump to any unfair and inaccurate conclusions. Certainly vertigo can have a wide range of causes, though it is even possible that anxiety or medications, themselves could be a cause. I hope the real cause of yours was uncovered.
