Sick

About a week ago I started coughing and snezzing. My family thought it was allergys a few days later we thought it was a cold. A few days later my mom was sick of me coughing all the time and haing coughing attacks and getting headaches from coughing so much. So she takes me to the docter's office. It turns out I have Broncoittis. Weird right? My cousin told me that you get it from having cold lungs so she's wondering how you would get it in the summer.
