I feel so anxious about Naegleria fowleri.

Question

A few days ago, my bottle accidentally splashed a bit of drinking water onto my nose, and now I've got a slight headache that wouldn't go away.

Case in point; our drinking water supply comes from a company that treats it with chlorine and other chemicals. And from what I've read, most of the cases come from geothermal water or hot springs.

Is the headache just my anxiety getting the better of me?
