Oh my goodness, story of my life. I get it all the time, and when I do get get it it lasts for days! I also have asthmas, so its very difficult to tell the difference between anxiety sob and asthma. It also occurs more when my anxiety/stress level is elevated, then I become more aware of the symptom. Ughhh I feel your pain. But try some breathing techniques, and keep up with your asthma and allergy meds to tackle both. Goof luck!
