Great posting.
Just a comparing note here. I did go through a period of this 'anticipation' as well. The way I delt with it was by holding an orange. Orange has uneven surface. I often held it in my healthy hand and felt it with the dystonic hand; always feeling the skin with my fingertips. While I was doing it, the seneation of 'anticipation' became less; it became a 'known' action, and no longer triggered the dystonic reflex.
I also used to write down my thoughts. When a fearful thought is present, I would write it down in my little notebook. It could be a thought about having a dysonic reaction, or something else. Once it is written down, the thought itself seems to lose its grip on me.
I have had plenty of fearful thoughts on dystonic movement. After writing down ever so often, this kind of thought lost its severity. And I could even 'anticipate' the 'need' of creating such thought in the first place.
It is fascinating to see how so many aspects in life are interlinked.
