Hi Brett,
I suppose a kinesiologist needs the understanding of brain trauma. Obviously he didn't have it. You see movement will return when your brain allows it and not before. I would say being a sportsman to not is a huge, massive change.

You need to concentrate simply on rest. You are bound to have anxious thoughts stream through your mind, but keep reminding yourself that this is the start of something new.
Even if you are not sure what.

Do not worry about tomorrow for it has it's own concerns I believe the bible says. It's so true, you have today. It will not count in the same way but you can create something worthwhile.

Your girlfriend maybe is angry because in her eyes it was a drunken stupor that changed you, she needs the facts. She needs to understand that this was a culmination of head injuries over the years but particularly the past 6 months.

Will be thinking of you. Try to do one thing today that you enjoy.
