I passed out the other day...?!

I passed out the other day...?

And I went to the emergency room because I passed out and couldn't come to for a while (10-20 min.) but my parents thought it was more like a sezure by the way I came out of it. When I go to the hospital they said I was dehidrated and the gave me and IV (:'( I hate needles) but to be safe they are getting me a E.E.G. (WHAT IS THAT?) and I'm really scared... I have one of these episodes a week ago WHILE I WAS BABYSITTING and I dont want to have what ever I might have but I'm soo scared! Can someone tell me what they are going to do? And what would happen if I do have the sezure thing?

it sounds like your in good hands
