I feel awful at the moment, but if I sit down for too long, and especially if I lie down or try to nap, I feel worse! My inner vibration really gets going, I feel worse and worse, so I might as well get up again. Despite being breathless on exertion I feel better for getting going and staying some level of gently active. So depressing. The only time I dare lie down now is at night in order to sleep. (My sleep is OK at the moment but I wake early with really bad inner vibration. I have to get up because if I snooze I feel worse!). Anyone else get worse when they rest?
