That's the way! I know exactly what you feel, hope you get well soon. When I had the flu for a couple of times in a row last year, I felt so weak I couldn't even play games or read. Later in the cycle I started watching TV shows, but I sometimes spaced out and had those weird fever-ish dreams of the TV show continuing in my head, it was frightening sometimes. And my entire body was aching, when I coughed and even when I just rested. It's only that bad for the first 2-3 days though. After that rapid improvements are guaranteed.
i'd go do some exercise or watch a movie. quickest way to heal is go see your doctor as i've tried diagnosing myself online doesn't do me any good and just leads to more costly remedies...
