Sick for over 6 months?

i had bronchitis during the summer that went away for a couple of months but not 100% then i got really sick in december and kept throwing up because of too much mucus in my lungs got sick again 2 weeks ago got rid of the cold but still feel like i have bronchitis. i keep throwing up at night from coughing too much. i tried 4 different antiobiotics, i also have albutrol syrup and enhaler that doesn't work even my codeine doesn't seem to work. do you think this could be a allergic reaction to my pet mice. i cough and gag more whenever i clean them. i had them since january last year. i cough like non stop. its very irratating. i even tried jamba juice with immunity and it doesn't work. my doc doesn't know whats wrong with me either. someone help.
