could i have been misdiagnosed in the 90s

when i was 16 on two occasions my parents came in my room around 5am and my eyes were rolling in back of my head and they could not wake me up
they tired walking me around but i was very limp . the first time they called the ambulance i went to ER and did an EEG but it was clear they sent me home
two days later the same incident happened this time the EEG showed seizure activity this was in 98 im 30 now

the neuro at the ER said epilepsy but MY dr at the time said he thought it was a reaction to the sleeping pill i was prescribed at the time he said it was too strong for a child.
but my DR said he had to go with what the neuro said

i have been seizure free ever sense taking 300mg of dilantin my levels have never been higher than 4.1.
i have now developed anxiety over if another seizure is coming

could i have been misdiagnosed back then or maybe the EEG went as good i have never had another one since

well in feb i went to see a nuero and he said that i would probaly never have another seizure again and it was up to me if i wanted to stop the meds.
then in june i went to the florida epilepsy foundation and he said i wasnt epileptic and to tapper off the meds
but i am scared because no one will give me an EEG they say its not needed

ok so an eeg doesnt prove much right
