Please let my body fight this.

Well, after a few weeks of feeling great, I feel like I am going down a slippery slope again.  I woke with a sore throat last week and figured I was getting a cold but unfortunately today, I woke with shortness of breath and chest pain.  I really hope that my body can fight this off.  I'm assuming that it is related to the cold but will probably know for sure by tomorrow and then I will either need to call the doctor or let it run its course.  I'm so upset because I was feeling good and really getting some great family time and now all I can do today is sit and watch the kids play.
