Was it Seizures or Anxiety?

Ok I have had SEVERE teen anxiety and still have it after turning 13 and it being 2 months later I wanted to know about this weird instance. Basically I had reacted to some Anti-anxiety Medicine VERY BADLY (Prozac) Caused me sleeping trouble, exhaustion and my Anxiety worsened within 3 days of taking it. Finally my mom dragged me out after over 48 hours of no sleep or physical activity. On the way there I finally lost it and had a either SEVERE panic attack or Mild Seizure. While Conscious I was out of physical energy having THE WORST Teen Panic Attack and then lost control.......if you know what I mean. Here ill describe it: I was aware and conscious but all I saw was a flash of blinding light lost control of my body and had the feeling of death (But was conscious during ALL of it). I was in the car and we were up high then my doctor decided I needed 2 be hospitalized even then these "Episodes" continued due to my fear and they last only a few seconds and I remember a few of the attacks. I would yell out and thought I was going insane and was light headed now im scared of my Anxiety and SEVERE fear of High open places. I have also have traumatizing thoughts of the old cartoon Akira...which my cousin & sister watched when I was 6 but I got over it. Mental illnesses run TONS in my family history, my dad also suffered from Anxiety/Depression during 8th Grade at 13. All want is a honest opinion was it a type of seizure or a SEVERE Panic brought on state? My mom thought it was just a Anxiety/Panic Attack since I haven`t had any neuro problems beyond Anxiety. But you HAVE to remember I HAD NO SLEEP FROM PROZAC IN 3 DAYS! Was it that and my Anxiety Fears?
