It is amazing how many different ways anxiety can manifest itself. There was a period of time, years ago, when my anxiety level was such, it caused my eyes to involuntarily jump up-&-down. So, of course, everything I was looking at fluttered the whole time it was happening.
I remember, one time, being at the Guthrie Theater to see a play. We were sitting in our seats waiting for the play to begin. I was looking down on the stage & it was jumping up-&-down like a Mexican jumping bean!
Warm wishes to you, Kiya...
