If : If i understand correctly. You are undergoing a neurological evaluation for these symptoms and are awaiting test results. In the mean time you are so upset that you have developed anxiety and panic attacks.

It : It would be inappropriate to even attempt to make an internet diagnosis of this complexity without a thorough review of history, exam findings, and all test results. I would pose a question to your neurologist, though, to see if vertebrobasilar insufficiency has been ruled out.
