Thanks Jubal,
I've still got a lot of work to do to get my nervous system happy with me again (so I need to take it a little slow and steady with getting back to work), but I'm really enjoying being able to use my eyes and ears more or less properly. ;-)
Psychosomatic symptoms are pretty incredible. I worked myself a bit hard last week, and combined with poor sleep and a bit too much visual stress from playing UnReal world on Sunday, I woke up Monday with some visual issues returned (pattern sensitivity and photo sensitivity). But, some exercise, regulating exercises (feet up wall), cold showers and things, and already within days I'm able to read books again and watch a bit of TV / use my computer a bit.
The nervous system can have an impact on so many of our systems, including vision, heart, etc. that we can easily mistake anxiety for all kinds of problems. ><
