See your doctor. If not, then drink lots of water, hot green tea or an tea you have on hand, rest a lot, sleep with head elevated, resist stress and noise. have some chicken soup when you feel you can. Do you have cough medicine or drops or lozenges on hand? Take good care of yourself, rest.
Could be pneumonia, call your family doctor and they will prescribe you an antibiotic and an inhaler. That sounds like a mixture of bronchitis and pneumonia to me, I'm no doctor but those are the prime symptoms of that. Hope I helped feel better!
