What type of illness do you think I have?

My symptoms are kind of common but extreme. They inlude, runny and congested nose, sleep deprovation (yet I am really tired.) I don't know how to explain it but my throught feels narrow or congested like i can't breathe (I have to drink alot of water just to speak clearly.) Fatigue. I got back from a basketball tournament on Friday where I think I got sick, although I have just started feeling sick yesterday morningish. I will get to the doctor as soon as I can, but until then, I would just like to know how serious you all think this is.
