First seizure

Hello, I have been reading the posts doing the looking for answers thing like so many others. Here is my story. I am a 35 year old male, don't drink or smoke, and have never done any drugs. I woke up with the Paramedics working on me telling me I just had a seizure. I was in the hospital for four days before they let me go home. I had the EEG, it was normal, blood work showed my potassium was low. CT shows a small calcium deposit on the frontal lobe. The Neurologist did not act concerned with any of this. I just had another EEG, it also normal, a MRI, and a MRA. The MRI and MRA results will not be given until my next apt. I have had the aura feeling such as da sa view before but did not know how to explain it. Until I had one in front of my wife, she made me see the Dr. Naturally the Dr looked at me like I was a freak and said I needed to see a Neurologist. The Neurologist ordered all the tests and when he heard I drove for a living wanted to put me on meds. I had been looking up the info on the meds and found out I could no longer drive wile on them, so the stress level went way up. When the seizure happened I was thinking about everything and was stressing out. I had no aura before it, I did not make a sound or bite my tong, or loose bladder control. While in the hospital my blood pressure was quite low so they took me off the bp meds that I had just started. I had been reading about low potassium and read it can cause, auras, low blood pressure, and seizures. The Dr. did a spinal tap to see if the calcium deposit is the Mexican brain worme, since I have never had a head injury. I suppose I will find out more next week, I hope.
