I don't think your anxiety and fear are so unusual after living for so long with unpredictable, overwhelming pain and spasms. And being a cancer survivor is a double whammy--living with the sword of Damocles over your head. My MVA was 9 years ago and I still have an easily-triggered startle response, which can set off my trapezius muscles.
It is wonderful that your surgery has been successful. I am a bit leery of saying that my surgery was successful for fear of jinxing myself, but bottom line is that it was indeed successful and now that I'm 2 1/2 years out, I am no longer constantly thinking that things could go sour at any moment.
I hope you can stick with your therapy and work through the anxiety and fear, taking control of your life so that you can begin to enjoy your success!
