D,

your nervous reaction is actually hurting your immune system due to hormone response. Chill the f out, take the steps David laid out for you above as it's all you can do. Worry, stress, obsessing is just going to hurt you physically, mentally and emotionally. Get a Xanax or ask a hippie friend for a brownie and watch some cartoons dude, or Pineapple Express, whatever takes your mind off of it until you get answers.
