What you are experiencing is normal, I think.
I'm 3 years in April and I still have times when
I feel leery of crowds. You can cope with this
if you just don't dwell on these thoughts--just
get out and do. Don't expect too much of your-
self, afterall you have had a major change in
your physical being which has had an effect on
your total being. When I started driving again I
used the back streets where traffic wasn't much
an issue until I felt comfortable driving--I think I
handled much of my recouping of abilities in that
way, cautious but determined!
Good luck! JanH
