I Have Been Sick With Cough And Chest Congestion For

I have been sick with cough and chest congestion for the entire winter( Jan, February now Ito March). I've had 2 chest x rays and diagnosed with bronchitis. I've had 3 rounds of different antibiotics (Cefuroxime 250 mg, Levofloxacin, and another antibiotics with light blue and dark blue capsule. I've seen my primary doc twice and and urgent care doc for the same problem. The cough is back with slight fever and I keep wetting myself. On one visit I insisted on the Rocephin shot for pneumonia but they wouldn't give me the shot. Please help just want to feel better and stop coughing
