Do I have bronchitis?

I was sick about two weeks ago,got better.Then I started having shortness of breath,a little wheezing and it hurts when I take a deep breath.Like I'm breathing in cold air even though I'm not.I also cough a lot at night when I'm lying down.I do not have a history of asthma and don't think it's as serious as pneumonia.I don't want to spend money going to the doctor either as I do not have insurance.Do my symptoms sound like bronchitis?Can I treat this myself at home?
