What Causes Wheezing And Difficulty In Breathing?

I have been very sick with an asthmatic type illness. I am a substitute teacher and had to leave school on Monday, due to feeling as though I were going to throw up when I bent over, not being able to breath,upper respiratory especially and nasal region. I took Benedril liquid, what I had left, have run out of my Zyrtec and get more tomorrow, am extremely weak and asked other subs to cover the rest of the week for me. I cough continually and am very weak. When I visited an doctor for allergies, her told me I was extremely allergic to Elm trees which are all around the back yard. I ride a lawn mower with a mask that usually works. This began to happen on Saturday with sneezing 9-10 times each and I rested, hoping I could work on Monday. My allergist it may also be dust and pet dander. When I mow there is a lot of dust and I do have two dogs and a cat who are my only family. I have rested now for two days and am not much better. I have been wheezing with strange noises coming from within my chest. I did not go to the emergency room, nor the same doctor because I feared it would be the identical respond as previously. I was just watching the news and heard about this virus that has affected many throughout the nation. I seem to have the same symptoms and they keep reoccuring, which cause me to be unable to sub. I could use the sub money, since I only have Social Security to live on at this point. I have been a Superintendent of Schools in SC and my friends can tell you that I am not over reacting or a hypocondriac who may think he/she has everything that comes along. I really need help and everywhere I turn, I hear you just have allergies like everyone else. My throat closed the other night and I had to drive to my neighbors and wake them up to help me. I could not speak to tell them what was wrong. They finally figured it out, knowing my situation. I see that there are no doctors available in WV where I live, but I could drive to Alexandria, VA if necessary. Could you help in anyway? I do not have a credit card to pay today, but could get one tomorrow at a convenience store and will continue to chat. Please tell me what to do?
