What should I do to cure this flu?

I’m battling a flu, on day two. Currently have a temperature of 99.9 degrees. My max temp recorded was 100.4 the other night. I feel the stuffiness in my head/nose region but nothing crazy like constant vomiting and such. Just the good old runny nose. I don’t feel hot at all in fact I feel a bit frigid. What are the basics I should be doing to ensure a speedy recovery? Thanks.

And please allow me to say, if you have a cold, please please please don’t go to crowded public places. This girl next to me in class straight up coughed into the air with out any protection of her hands, inside of elbows etc. And then I got sick. :(
