Hi Kate, Sorry to hear about your seizure coming back.
My youngest son had seizures for several years. When he had his first seizure he was about 6 years old. I was a JW but at the time separated from my JW wife and not attending meetings.
The elders suggested to my wife that his seizures were most likely demon attacks because I was not being loyal to Jehovah at the time. They used the scritpure in Mathew where the boy had seizures and was demon possessed to back up their claim. We did find some medications that did a good job of combatting those demons.
There are some good medications to help with this so visit your doctor if you havent in awhile.
All the best.
