Get your butt back to the doctor missy. And get a strep culture.
But in the mean time:
Get some chapstick for your lips. Straight up old skool chapstick (doesn't matter what flavor). Avoid the caffinated tea (will dehydrate you).
Gargle with salt water as hot as you can stand it.
Add Honey to your tea
Get some Sprite and OJ
Ludens makes a good lozenge
