I'm a hypochondriac? I was in a car accident and I been laying in bed most of the time.

I took a sip of water as a laid and now I'm thinking I have brain eating amoeba. I just don't have friends and I need someone to calm me down. I don't drink tap water but I drink purify water that has been treated by reverse osmosis, but I'm paranoid because I drank sprite from a styro foam cup from chick chick Fil A. I did it such a way that I basically laid down in my bed really quick and I keep thinking the water went to my brain was I laid down.
