BEEN SICK FOR OVER 1 WEEK WHAT SHOULD I TAKE?

I've been taking plenty Vitamin C; Garlic; and Acidophilous. Been drinking warm tea with lemon and honey; plenty of water; Robitussin DM; Alka seltzer plus; and sinus medicine at night, nothing I know to do seems to be helping. My head is stuffed up; my throat is soar; and all my lymph nodes in my neck are swollen and tender as hell. Today my chest is feeling tight. I'm getting worse, not better.WHAT ELSE CAN I DO??? I'm going to the Dr. Monday if I can't fix this. Oh, and I've kept the house humid with boiling water and humidifiers.
