Brain eating amoeba are you concern about it have you ever gone swimming in a lake, river, or water park?

I have this bad custom that I develop 6 years ago where I will sometimes drink from the fountain drink I bought and place it next to my bed and take sips as I particular laid in bed, until I realize that brain eating amoebas existed it through in a panic mode. I only drink purify water bottle and yesterday I had a Sprite from Chick Fil A. I'm so worried because I drank the sprite basically laying down. I keep thinking maybe the sprite reached my brain as I laid down.
