Please be very careful in your recovery. TBI is a funny thing; you can feel fine, but you are not. Are you going to be working with specialists to assess you as you recover?
There are plenty of people here that have been through this, but I also recommend sending Denise Goldberg a note. I have ridden with her a bit (after her crash) and her recovery story is inspiring. She has a blog and a website.
