I am beyond anxious and stressed. Monday September 16th I was paddle boarding in Austin Texas (in the Colorado River under the Bat Bridge) and I fell in. Upon falling in I took a load of water up my nose. The minute the water went up my nose I instantly panicked about it including naegleria fowleri a brain eating amoeba that just killed a Texas girl in the last few days. I am absolutely terrified. I spent all of last night sobbing between panic attacks. Today I went to the ER to get more information on it and they told me that they can not diagnose it until I am showing multiple symptoms. Right now I only have a headache (which rationally could be from all the crying - however - my anxiety is convincing me otherwise.) It takes 1 - 15 days for symptoms to appear and if they do is 99% fatal within 3 days. I am paralyzed by fear and even called out of work. Any advice on what to do would be appreciated. All I can do for the next 15 days is stress in copious amounts.
