A lot of things can make you wheeze; asthma is a disease that can't really go away, it can just get better and go into remission, etc. I had to go to the ER 3-4 weekends ago with mine, they started me on steroids (which my own health care person and I got me off of right away as I didn't need that full-blown help) and now I'm 100% fine; I have trouble in the "summer" for whatever reason, especially in August. Probably 80-90% of asthma is due to allergies. Emotional upset doesn't "cause" asthma but doesn't help it either. It's kind of like when you have a cold and how that doesn't help anything because you're already stuffed up and having trouble breathing. Emotional upset causes problems of its own but if the asthma or bronchitis is under control with control meds, shouldn't cause an attack necessarily. Anxiety can cause wheezing of its own, as in panic attacks but none of that is related to asthma or bronchitis which is caused by gunk getting trapped in the lungs because the lungs overproduce it during an attack. I would say you can wheeze when you get emotionally upset but that isn't your bronchitis or asthma, it's the emotional upset causing problems of its own.
