My Very Terrifying Experience in Wal-Mart

So I was hanging out with my best friend at Wal-Mart and browsing the stuff the store had. At some point, I wanted to test out a bike with training wheels and give it a bit of a whirl, but it triggered my muscle jerking/twitching issue I've had for a few years now. For the muscle jerk/twitch issue, it's where my arms spasm or jerk without warning. I have no control over this, but it's usually only one sudden jerk, which I am fully conscious during. I usually laugh or shrug it off when someone gives me a concerned or vaguely judgmental look. But...when I was testing the bike, I had about three or four of these jerks/twitches, so I decided to dismount the bike since I had a feeling it was my body's way of telling me to stop. But then we passed by where they had skateboards, and I took one out to test it out. I was very careful with my footing and was gonna only push myself forward on the skateboard for, like, a foot or so, but then my legs started jerking and twitching out of nowhere and gave out from underneath me, causing me to fall off the skateboard and twist my ankle, which I DEFINITELY felt. I was about to cry out in pain and grab my ankle, but then my arms (both arms) started jerking over and over again, flailing in the air, and I wanted to cry out or stop my arms from doing that, but I watched my body spasm faster and faster and the muscular jerks increase over time until the entire world right in front of me started to shake and go into slow motion. I tried to reach out or yell, but I couldn't move anything in my body at all. I watched my entire body convulse and shake, and it was so frightening since it was the very first time I had ever had that kind of seizure. Then I blacked out before I knew it... And woke up in middle of the aisle with very worried paramedics surrounding me. I was deeply confused but assumed I probably just laid down in middle of the aisle and fell asleep or something, so I laughed it off, despite seeing my best friend standing a bit far away from me with a very worried look on her face. I just assumed she seemed worried because she probably turned around to see her best friend asleep on the floor. I mean, I'd be confused too. But the paramedics kept asking if I was okay, which I kept waving off, and then they said I was going to the hospital. I tried insisting that I was fine, but my best friend shook her hand and told me that I had a seizure. Right when she said it, I then suddenly and immediately remembered everything I had personally witnessed from my seizure right before my blackout and was immediately stricken with a very severe anxiety/panic attack, pretty much breaking down right there and then. But I was taken to the hospital...against my will, which was probably for the best since I was being really stubborn. They tested my blood and urine and gave me a CT (CAT) scan and told me everything was fine before prescribing me on Keppra and directing me to a neurologist, which I am supposed to be calling in a few days. But since that experience frazzled me so badly, I'm frankly terrified of contacting the neurologist because of what I've heard about EEG testing and how they trigger seizures. I definitely do NOT wish to have another one, no thank you. So some input or advice would be greatly appreciated. If you have had a similar experience, do not hesitate to type about it. Thank you. Also, in advance, I do have family history of epilepsy, but I have not been diagnosed with it yet.
