I completely agree that you need help *now,* and I hope you do.
My asthma has gotten a lot worse over the last several months. I had a relentless cough. Using a steam humidifier helps. I have to have one at my desk at work, and sometimes while I sleep. I also have to use a neublizer machine during the day to keep my breathing intact.
Bottom line for you tho, is that you must get help immediately. Please keep us posted.
