Was I misdiagnosed in hospital after having 2 seizures that no one seen but my parents whiie I was sleeping 1 postive EEG 1 negative I was 16. 30 now?

Memories 14 yrs ago? There is no way to tell without all the details from that time 14 years ago, so one can go see a new neurologist a couple of times to together decide if it is worthwhile to go back in time. Sometimes there is a need to know exactly what happened. Other times, patients can be treated according to their present status without fully knowing what really happened long ago.
Don't know. I would see a neurologist now and probably get another eeg. Especially if you haven't had a seizure in 14 years.
