What is wrong with me? Please help!?

In early December I got some sort of bug. I had swollen throat glands and a stuffy nose. After weeks on antibiotics. I stopped taking them because I was feel better, I mean no stuffy nose and rarely phlegm when i coughed. But i woke up in the middle of the night yesterday with my throat really sore. I got all the symptoms back from the bug I had before and I had eye crust on my eyes. Except now I do not have mucus in my throat. It is just sore. Please help!
