I recently came down with the flu, while my mom was at home, in another state. Let me tell you how much it sucks, when your mom isn't there to make you chicken noodle soup and make sure you take medicine every six hours. Mom's also just happen to know everything about whether that runny nose and cough is just a cold or something that you should go to the doctor for.
My first bit of advice is when you call you mom, dad, or other loved one and say you aren't feeling good and they response with go to the doctor, actually go to the doctor. Don't be a hard head like me and insist it's nothing and then wait a couple days until you feel ten times worse to go. The sooner you nip something in the butt, the better. And once you have been diagnosed with something, make sure to stay as far away from friends, roommates, etc.
Staying hydrated, getting some sleep, and taking whatever medicine the doctor prescribes you properly are the easiest ways to start feeling better. Gatorade, ginger ale, or simply water are all great options for sick people. Also, lay in bed and caught up on whatever series you've been bingeing lately and make sure to take your medicine correctly and for the entire time it says. These may seem very straightforward but sometimes being sick gives you scatter brains.
It's also very important to have take some Lysol or bleach wipes and sanitize the areas frequented right before and during your time sick. And also, wash your bedding when you start to feel better. Most of the time mom's are there to do this but, when they aren't it's up to you. And trust me, it'll help you to stay healthy and not to give all your friends and roommates whatever sickness you had.
And most importantly whenever you are sick, your mom is just a call or Facetime away!
