Betrayal ?!

My body betrayed me today.. I do not know how to explain what is going on. First thing this morning, I rushed around preparing items to take with me if we have tornado damage and need to evacuate. A shower followed by clean clothes, blue jeans rather than a dress or skirt. On the computer monitor (Internet), I started watching/tracking the tornados in Nebraska and Kansas. At this hour (4:30) I see the storm has reached Oklahoma. Lookng at the trees outside my windows, it has gotten very windy in Waco. However, hours ago my body was drained of every ounce of energy, and incentive. I have alternated between my recliner and my bed. All I want to do is sleep. I didn’t go to lunch and I won’t go to supper. Malaise?
