I understand your feeling bad about this happening. I have had grand mal siezures from ages 4 to 14 and I thought if they didn't stop then I would never be allowed to drive. My mother was so protective of me and still is to this day. Well when I was 14 I started taking Phelbatol (which is now off the market)and it seemed to take away all the seizures and I was so happy. I had lost all the weight thst I had gained due to other medicine and I felt like a new person. Things went good until I went to see an allergy dr (I never was allowed to take allergy medicine due to seizures) but now I could, great idea right? WRONG!!
After informing the allergist that I had a history of seizures, he put me a couple of medications and that was when disaster started. About a month later, I started having tiny seizures(petite mal seizures). I wasn't sure what they were at first, it was like my head knods back a couple of times and I lose concentration for a split second and then everything is back to normal. I was so worried but the dr told me that if they didn't bother me then I wouldn't have to go back on the meds. Well, I am 21 now and still have them, they are more embarrassing than painful.
I really know how bad you are feeling now but who knows, maybe the lord will bless you and you won't have another one. I really hope that everything goes well and please don't let this get you down. Sometimes there is nothing you can do but except what God has handed you and do your best with it.
