Hi Dean, you're not crazy at all man what you describe is almost identical to my "condition".

As much as people wants to say it's anxiety it's not. As you've probably realised there is so little information on this will you issue of "ongoing brain sensitivity caused by concussions" or whatever you want to call it.

Let's get in touch and talk, it got me so depressed beyond belief for a long time when I first developed this but it does get a lot better.
