Why is this happening to me?

Hi Rachel. You need to go back to the doctor and get a proper diagnosis and treatment. It may take a few visits, some tests, perhaps a referral. Nobody can help diagnose you here. My immediate thought was a sinus infection and you have anxiety that is getting worse because you don't know what's wrong. But that's just a guess and it could be many things going on. Please go back to the doctor until you are satisfied and feel better.
