What are some good ideas?

I have been VERY sick with bronchitus and now I am over that and am still coughing SO bad and my chest hurts EXTRMELEY! Have been to the doctor more times than I can count, they don't know what's wrong so I am waiting to see a pulmonologist But here's my problem. its embarrasing to go to work and cough like that, i almost p out from coughing & how are you suppose to work when your chest feels SOO congested but supposedly it's clear. I am sure the doctor will write me an excuse to miss work but what do i do in the meantime? i miss work yesterday and it caused a big fight between him and i--he says he would go to work if he was dieing, but he doesnt feel how i do..short of breath etc... I dont want to cause any more trouble between him and i but what do i do
