Is this an anxiety symptom?

It sounds as if this could be an anxiety attack, but your symptoms seem fairly severe and possibly dangerous. Your symptoms also resemble a blood sugar problem! As always the VERY best thing to do is to consult your primary care Dr. for either treatment or a referral to a specialist. My heart goes out to you as this must be very frustrating and frightening. Please see your Dr. as soon as possible for you own best interest! By ALL means try not to drive under these conditions not only for your own safety but that of others on the road! I wish you the best of luck and God bless.
