Rubber legs

Last night, during the night, I got up to pee and my legs had turned to rubber. I could barely walk at all. I went on-line and entered "legs turned suddenly to rubber" and learned that this is a common symptom of anxiety and stress! I had never heard of this. It described very accurately what I had experienced and said it was common for people who experience this to think they have some dread disease, like ALS or something. That's exactly what I thought. I was relieved to learn it was anxiety. I went back to sleep and this morning my legs are functioning fine. How weird! I wonder, with all the anxiety over this upcoming election, how many rubber-legged people there are out there?
