Sick for 3 Months and nothings getting better.. : ( please help?

Ok i have been sick for over 3 months now, this all started with normal cold symtoms.. then week by week my symptoms would increase.. around the time of the superbowl i had a really bad cough, sometimes i would cough so hard that i would throw up. The doctor gave me Benzonotate, which helped but not really. Eventually the cough chilled and then a week later i had a really bad middle ear infection in my left ear, my ear was bleeding for 2 days and i was on Oxy's for the pain. A few days later the ear infection is gone but my ear feels clogged to this day. Then a week later i had a sinus infection with dizzy spells, was taking R-tanna, then i had a swollen gland and doc gives me Omni somethin for antibiotics.. another week pes and my cough is back, and now i have swollen gland on my right side and i have a sharp pain when i swallow that goes up to my right ear. i dunno what to do anymore, i am constantly sick and finding it hard to function sometimes..how can i finally feel better??
