I am 18. A few weeks ago i was sitting at my desk and suddenly all the noise in the room seemed to have gotten very loud. I looked up, and everything looked blury, I tried to get a hold of myself, but everything was getting more loud and more blury and distorted. Suddenly the whole area around me started to be black, as if my eyes were turning in their sockets, and I became unconsiouss. When I woke up, an ambulance was there, and I noticed saliva all over my desk. I was able to control the rest of bodily functions however. I felt extremely week when I woke up. My sugar level was taken, and it was 2 or 3. I was given a 50% solution of "sugar water". I found that their might have been a mistake when taking my sugar level, as I had quite a large lunch and drank grape juice, had pizza, etc... I was taken to the hospital and when I was in the hospital, I felt significantly stronger. I was given several tests. I was given a blood test,ECHO,CT,Halt Monitor,EEG,and a complete cardio check up. Every test came back normal. This has not happnened again to me. However, I've been getting strange symtoms. It's like the occurence is happening all over agin. Noises are getting louder, the world around me looks blurry, I basically have strange sensations in my head. However, I am able to control myself, and return to normal in apprx. 10-20 seconds. This however hasn't happened in apprx. a week. Do you think the first occurence was a seizure. And the second occurences were "aura's"? Could the 2nd ones be anxiety attacks, and what do you think the first thing was when I passed out? Thank you!
