what could I possibly be sick with? Please help! easy ten points!?!

I went to the doctor today and got a strep test, it came back negative.
here are my symptoms:

Sore throat that came on suddenly yesterday afternoon, got slightly better this morning but still hurts terribly, I couldnt swallow and was spitting out my saliva because I couldnt swallow.
Dry cough
muscle aches/extrremly sore
exhausted
feel like my body weighs ten times more than it actually does, hard to keep my head up
runny/stuffy nose
dizziness when standing
confused sometimes
hard to breath sometimes
shaky

do any of these symptoms match a virus and/or bacteria? thank you so much for your help!
