i am almost 14 and i have been experienceing head aches since i was about 8 or 9. and over the years they just keep getting worse. this past summer my headaches were crazy. i went to a eye docotors to see if that was the problem, they ran a test and said it couldn't be my eyes causeing the headaces. i went to the doctors but they said it was stress. but i think its more then stress.

and sometimes during and after i have a dance class or gym, i can only see the colours black and i become very dizzy. but i can still hear everything that is going on.
i am concerned the headaches are related to my blackouts.
And i have noticed that when i drink pops with a lot of sugars(sprite,rootbeer.etc) i get headaches.

wat could it be?
