Suggest Medication For Respiratory Tract Infection

I had a respiratory infection for a few weeks, went to the nurse practioner and she gave me amococillan, did not work but took for 10 days, then say my doctor and he said I had a bad sinus infection and put me on a different antibiotic took ot for 10 days felt better for 3-5 days and the runnny nose, watery eyes, cough, coughing so hard was losing my breathe, urinating in my pants and eventually throwing up. Whenever I went outside even just from the house to the car it fel like my lungs were closing. They put me on another anibiotic that kills the good and bad and gave me to inhalers.. Going outside still is a problem and my chest hurts all the time and I am completely exhausted. My body hurts
