Been sick for a week! PLEASE HELP!?

on Saturday (my birthday) I was really tired and sluggish and felt very nauseated so i took a nap and i felt like i was getting sick, then on sunday i had to go to brunch with some friends and i had to go to a charity thing with a bunch of people and thats where i started to feel completely terrible because it was so crowded and hot and loud, then i went home and i fell asleep in the car and got a terrible headache and then i fell asleep on the couch and missed church. ive been sick every day since with a fever and a terrible cough that sometimes is mucousy and other times is dry. I went to the doc because my mom thought i had strep but im negative for strep and flu as well. the doctor said it was viral but didnt give me any anti viral meds so i feel great after i have tylenol but when it wears off my fever inclines, its gotten up to103. PLEASE HELP!!!! i might miss CPR training and like all of my midterms if i dont get better! and ive already missed too much school!
