Hi. I don't agree with your doctor that this is just stress and depression.
First off it could be an interaction between your blood pressure medications and the antidepressants or just from the antidepressants alone.
But the problem could also be either transient ischemic attacks--threatened strokes--or an inner ear problem.
Dehydration is another possibility, as is anemia.
I personally would get an MRI of your brain, a full cardiac workup, and full blood tests.
You need to discuss all this with your doctor
My Dr will just say its not needed
Perhaps but you still need to discuss this with him Julie.
I can't influence his decision--all I can do here is give you my thoughts and opinions and what I would do were I your doctor.
At least ask your doctor about the things I've mentioned and let me know how it goes for you.
