I must be missing something but, I don't see how anti-depressants can help with dizziness. In fact, I think dizziness is a listed side effect.
I wish I knew more about adrenal issues but, I don't.
I guess she's thinking the dizziness is related to your adrenals (could very well be based upon other reports I've read on forums) but, again, I don't know enough about adrenal issues to feel comfortable in commenting about anything.
I hope your bloodwork provides helpful information....at least you'll have an idea about your thyroid.
You know we're rooting for you!
