Really sorry to hear of your crash and bad injuries, robabeatle. Good news the doc says you'll be back to full function.
I've crashed a few times and always feel freaked out getting back to the same situations that the crashes happened in, but in time, that mostly went away. Just give yourself time to get through the feelings you have about it, they are normal and will probably fade. I took "baby steps" getting back to crash situations - solo and then group rides before crits, for example.
