Does anyone have any idea how to get this cold out of my chest?

Seriously, I can’t take it anymore. I feel like death and my lungs are on the verge of collapsing. The muscles in my back are so sore from coughing that I can barely stand. I may have to go get some kids Mucinex cause I can’t swallow big pills.
I have spent the better part of 2 days with a heating pad stuck to my back and Vick’s rubbed over every part of me.
Someone please help?
