I've had something similar (post-concussion syndrome) that's slowly improving, though I'll never quite be the same. You live a life where you're intelligent and capable and happy and then it's torn away from you. You remember when you were capable, but you can't do it anymore. Somehow the things you learnt on a whim before it happened become your defining knowledge. What was trivial becomes incredibly difficult; what was difficult becomes impossible. I'm mostly over that now, fortunately. But if it were permanent I'd see it as a fate worse than death.
