I'm Sick, AGAIN!!

I'm sick again! It doesn't seem like it's all that often that I can write that I'm not sick! This is the third illness in as many weeks! Today, I have my "sexy" voice. That just means that the congestion has moved to my lungs, and my voice is finally beginning to be affected. I haven't been to the doctor but I'm wondering if I should be looking into a Blueair purifier. Could something in this air be making me sick constantly?? I'm the only one in the family affected with constant sickness, it just makes it hard with four kids being left to tend to themselves while mom is incapacitated!!
