Do i have epilepsy?

Hi!I recently have had an inncedent which may be the cause of epilepsy. I'm not sure whether i have it or not, and was wondering if anyone could help?I am 17, and ever since i was very young, around 5 or 6, i have had 'miagrian seizures'. These seizures are totally mental. This would always happen before i got to sleep, or when i just woke up. I have had minor shaking, but the main symptoms are like explosions in my brain. i hear voices, see things, and get very very confused. I can't remember what i'm doing, and everything i hear is in fast forward. Its sort of like all the sounds i interpret are in a 'chip-munk' voice. It was very very scary when i was young, but by the time i had reached around 10, my parents noticed them and i was rushed to a doctor. He first was sure they were symptoms of epilepsy, and i was taken to have an EEG. this came out clear, and we heard nothing of it.I'm now 17, and recently have had a fit. I was coming back from a 'festival' and had got hyponotised. I came out of it pretty confused, but went on with my day. That following night, i went back to a friends house, and they were smoking weed. I didn't smoke any, but i breathed some of there second hand smoke in and couldn't stop vicously coughing for about 20 minutes. After i felt really really woozy and i couldn't see well because i had black dots in my vision. I have smoked weed in the past, and have been fine.When i got home, i went straight to bed, and this is when i had a fit. I violently shook all over from my head to my toes. A few people had to hold me down so i wouldn't hit my head. I kept waking up and passing out every few mintues. Everytime i woke up, i couldn't hear well, and couldn't concerntrate at all! I would forget what i was saying half way through sentences,and i couldn't respond to questions because i would forget them in seconds. The most scariest things were, was that i couldn't talk. I could only talk really retarded. Really slow and slurred. It sounded like i had a stroke. I also couldn't move my arms or legs, and they would just stop in mid air and i couldn't move them. It felt as if my head wasn't attached to my body because i couldn't feel anything. I also kept having flashs, and would stare into nothingness. My pupils were fully dialated (my friends said i had jet black eyes) and i couldn't keep my eyes in one position. I couldn't stop them from either rolling back in my head, or crossing them. It was so hard to focus. My friends also said my breathe smelt like tea. This fit lasted 3 hours, and at the end, i feel alseep.The next day i was exhausted! I slept all day, and my body felt like lead. I was still confused and couldn't remember too much about the night before.I haven't told my parents because i'm scared it may have been the pot, but i also have my doubts about the hypnoses. Can anyone help? I'm sorry about the big story, but i am trying to explian everything in as much detail as possible.Thank you so muchAshley
