New to seizures: Confused & Scared

Okay I'll start off with the beginning: A couple weeks ago I had my first seizure I don't know what kind because I am not entirely sure how conscious I was for it... If that makes sense. I was riding home with some friends and felt car sick which I never do, then I threw up passes out and next thing I knew I hear "she's having a seizure pull over" and I vaguely remember convulsing... They took me to the ER whom aggressively yanked me up and then I went into my second one.... After being in the ER they said "I was carsick and have bad anxiety attack and I don't know what a seizure is, and we don't know what happened but it wasn't a seizure" even though I seized in the nurses arms.... A couple weeks later (a few days ago) I seized at work and I remember ringing up a customer and I couldn't type on the keyboard I kept hitting keys with my hand but it wasn't what they were saying, and I apologized and started again and I couldn't control what I was typing and then everything sound wise faded out and I collapsed and woke up seizing according to the school nurse I was ringing up I had a tonic clonic seizure, she said I went for nearly a minute but I only remember 10 seconds.... ER was called took me in an ambulance and wrote on my diagnosis: "migraine" "convulsions" "anxiety"..... I now have appts with a neurologist and scans for EEG and MRI coming up but my questions are... 1) can you seize and go unconscious and come back near the end? 2) am I as crazy as the ER makes me think or did I have a seizure? 3) a lot of people are saying it could psydosezires meaning all in my head, I really doubt that's the case how do I know the difference? 4) can you seize and not pee your pants or bite your tongue? 5) so far there are no links or triggers or auras to either of them so is it epileptic even with no triggers and auras? 6) I have had severe nausea more in the esophagus like that burning feeling along with a headache for days after it is that normal? 7) after my seizure I have this dazed and out of body in a dream feeling and I was told its anxiety, am I doing this to myself? 8) What do I do about work if I can't drive or function? Should I go anyway? And hope it doesn't happen again? 9) I don't have a history of epilepsy but I do have a history of migraines for nearly a year and then I had my first seizure a few weeks ago? Is that normal? I know I have a lot of questions but with medical professionals making me feel crazy, and not knowing a lot about this I thought who better than people who deal with this and can show I'm not alone.... I appreciate any time you take to read and reply, thank you.
