Could this be bronchitis?

I was sick for a whole month, with flu and cold like symptoms, and am just getting over that, but now have some new symptoms that have been going on for about 4 days:A little bit of mucus, feelings of faintness, sore neck that only started tonight, feeling so exhausted, that I can't even cough without wanting to gasp for air. And I can't even cough fully either. Can this be bronchitis or anything else? I don't smoke.And I'm making an appointment tomorrow.
