RE: Being sick as an adult is no fun...
I think the hardest part about being sick is how much rest you need to get better. Life really doesn't stop or is patient enough to wait for you. Indeed we have many responsibilities now and expectations. We have to be determined to fulfill some of them while taking time to rest often and pace ourselves. Which is very hard to do.
Another is being sick and not having the company and comfort of others. When we're sick we may feel too prideful... Rather not be seen weak and venerable. It is nice to have company that persists to be by your side when you need it most. Same goes for family. There is also a sense of accomplishment about completing all of your duties while recovering. It is satisfying to make it to the weekend after a long week of being sick and faceplant into the bed.
Hope you feel better @omnithumbs, take vitamins and have lots of soup. Hope this bug passes quickly
