Are my asthma symptoms typical?

I have been dealing with asthma for about 2 yrs now, and i seem to have it under control, unless it is very hot and humid, or extreamly cold. i work in a factory and this can be a problem during the summer months, and i tend to miss work. I am currious about my symptoms, I do not have any weezing (which I hear is common), but I have trouble getting air in, I try and take deep breaths to get air in and of course i can't. This leads to me becoming extreamly tired, light headed, I tend to have panic attacks & my throat tightens making it even more difficult to breath, i also notice that I yawn alot when I start to have trouble breathing. I have recently started getting migrains, and i am not one to get headaches. I take my symbicort regularly, and use my emergancy inhaler when i need to. However, sometimes it does not work-ususally when it is extreamly hot & humid. and i am not always sure what to do when i have an attack.

I guess i was wondering if this is what it is like for everyone else? does everyone experience it differently? And what do people do when they have an attack? What am I suppose to do? (My dr. was not very clear about these things)

Thanks!!
