Steve,

As another person who has done vision therapy a while back, what Mark is trying to say is the people who this stuff is really going to help are the people who like can't read text because the words are moving all over and are blurry because their eyes are either not working together with one another or with the vestibular system or both to form a stable image. There is a multitude of issues that people deal with, but you would really know if this was an issue for you.

Not sure, but it seems like, using your devices just got you riled up a bit and got your anxiety going. If anxiety is your only symptom, none of these other therapies are going to help you. Your initial injury is healed. Count yourself lucky that you don't have any other lingering symptoms. Though I know anxiety is terrible to deal with, it is treatable. Do CBT, exercise, sleep well, eat well, take care of yourself.
