Start boosting your fluids and make sure you're getting your electrolytes. If coughing irritates the throat make some honey lemon tea. If you start sweating from a fever lay down on a towel and change it out when it gets wet - dont let cold wet blankets make you feel worse. Sipping warm broth is a nice savory alternative to sweet drinks to stay hydrated and put something warm and soothing in your stomach. If coughing causes muscle discomfort in your chest do some slow breathing exercises and stretches to keep your muscles limber and relaxed. You might find pairing that with a hot water bottle or heating pad to be even more effective. Best of luck. And hey, venting is okay, it's a good way to get out some of the bad vibes, mental health is good for your physical recovery too.
