Do i have... mono?! please help!?

okay so on new years i made out with this guy at a party and my throat started hurting a little bit the next day, and it went all bad yesterday. i broke out with a fever. i had a headache, the chills, and the side of my neck was a little sore. also when night time came around, i started sweating a lot. and today i woke up and my whole neck was stiff and hurt a lot, and my throat had all this gunk in it + it hurt so bad to swallow :( it still does. i tried cough drops and gargled salt water for 30 seconds but it still hurts just as much. i have a huge headache and fell asleep for a couple of hours but woke up feeling really crappy :/ i look like a zombie its all bad! do i have mono?!
