Bizarre and terrifying derealization experience--panic attack?

28. I think it was some sort of seizure

The more I read about seizures the more I think I had one. The whole ear ringing and visual perception alteration seem more akin to something happening in my brain. Both my brother and sister have partial simple seizures. They said my "episode" was similar to their partial simple seizure, though mine lasted much longer than anything they've ever had (theirs last maybe 2 minutes, max, mine was 4 hours. I will be meeting with a neurologist but I'm not hopeful for a diagnosis. Both my brother and sister had normal EEG's, etc. My sister had these for years, since she was a teenager. She started yoga and meditation about 10 years ago and hasn't had a single seizure since. My brother is in a high-stress job, doesn't eat right, doesn't exercise, so continues to have his partial simple seizures.

Since my stress has been off the charts and I was also getting maybe 4 hours of sleep a night for several days in a row (I have Restless Leg Syndrome as well), I'm leaning towards a seizure.
