Lastly i have been having these dizzy spells.. for some reason the bright lights in schools, or malls, or even in my daily life of looking at things.. but it comes and goes, and sometimes it stays for a long time.. i dont know if i have eye tumor or somthing.. should i see a eye docter? i mean last time i went my vision was 20/20 and im 17!?!? Could staring at the Computer trigger my vision? when i was little it didnt.. and sometimes i feel i cant think .. am i just worried about things alot.. i seem to creat an illusion to make me think something is wrong or somthing??!
