If you have been feeling a bit under the weather, but can't get a doctor's appointment until Thursday at lunch, do not, under any circumstances, go on the internet to try to figure out what's wrong with you. Because every disease is worse than the last one, and they're all fatal, or debilitating, or worse, and the anxiety alone from your "research" will probably kill you long before you ever figure out what's really wrong with you.
Just thought you should know.
