What drugs are you on for other conditions? You are a 17 year old dude in 2009 so i would guess that you are on some fuked up kind of drug for depression, adhd or something else, whether or not you really have the condition.
Been taking anything over the counter or had a drastic change in your diet around the same time you started to get sick??
And WTF... is it strep or the flu?? There are reliable rapid strep tests that all doctors would have. How do you not know for sure that it is or not strep? What kind of doctor do you have?
