Could I be having partial seizures?

For at least 6 years now I have been having strange neurological activity. At first it was just a sudden pain in my head and I felt like I was going to die. It would only last for about 30 seconds. Then I started having sudden extreme blood pressure spikes with great anxiety (some panic attacks) and very crazy feelings in my head. Now the blood pressure is under control almost all the time, but I still have crazy neurological activity. Sometimes this causes my blood pressure to go up, but I think only from the anxiety and feeling like I am dying. Today while driving I felt a "wavelike" feeling in my head. Shortly after I came to a stop at a light and I felt like I was still moving and had extreme anxiety. I have gone to the ER many times thinking that I am having a stroke or heart attack. I have nothing wrong with my heart. I have had some CAT scans but no MRIs on my brain. Nothing wrong showed up on the CAT scans I suspect that I may have adrenal fatigue and maybe hypoglycemia. I have done some colon cleansing and I am eating a gluten free diet and no Sugar diet. Has anyone ever had similiar symptoms? Could I be having partial seizures?
