I Was Sick For Approx. 14 Days With What I

I was sick for approx. 14 days with what I think was a bad cold. It started with a sore throat and on the 2nd day, I had lost my voice. I developed a hacking cough that worsened at night, but did not produce much mucus. Around the 5th day, upon waking only, I had a lot of thick, dark green mucus when I would blow my nose. I began taking amoxicillin that I had from a previous cold, and the mucus dried up, but I still had a low grade fever. Now, 14 days later, I am still coughing a little and still have a little mucus production, but I have started feeling lightheaded and I am very fatigued. I also have the periodic, split-second feeling of losing my breath.
