Light Headed / Dizzy Spells - Happened Again Today While Driving?

Let me start by saying that I am diabetic and also do hold high blood pressure (both are monitored and for the most subdivision controlled). I also just have several tests run as I was have heart palipations (they did an EKG, Stress Test, Holter Monitor, etc), to which they have ruled "palipations" from stress, etc as zilch was showing up in the test. Today for the second time this month I had a desperate spell to where I feel like I hold to "squich" my eyes and like I be going to pass out while driving. After this occured my heart be racing and I did hold palipations, but this of course could hold been cause from the pure anixety of the "spell". My blood surage was not low, be good for the reality that I had lately ate and when I got home my blood pressure and heart rate be good (did not hold a monitor with me to check when it happened). I did take hold of an aspirin and pop it in my mouth, just surrounded by case. But presently I am fine? This is caring me? Any design on what could be wrong/happening?
Answers:

Why am I urinating so much?

Are you dehydrated? Have you started any spanking new medications? Take your monitor next to you for the next time you own an episode. Check your urine. Is it a nice straw color or is it dark or too bedside light? Do you take your own blood pressure? You call for to take it when you enjoy an episode to rule out if your BP is too low at certain times of the time.
