I think i have a brain eating amoeba. i have been having headaches for the past week with some nausea when i get extremely anxious. no fever. no vomiting. i went to the er, they did a ct scan last wednesday. everything came back normal?

Naegleria fowleri: If you had this infection for a week, you would be dead by now. And the CT scan proves you have no such thing. I believe you have asked other questions about this very rare infection. You may be obsessed over it, a form of germophobia, which can lead to devastating mental health consequences. (See the movie "The Aviator".) Speak with a doctor about possible referral for counseling. Good luck.
