oh gosh, yes, be kind to yourself..
do you do any meditation? I always thought of myself as a strongish person, but this anxiety has got hold of me...
just saying.
I wouldn`t go out after dark,, I have ensured that I get back as dusk falls if I am out late afternoon..
take it slowly is what I would do, a little bit and a little bit, ie. short walk,, build up your confidence again.
I am assuming your dog was with you when you were struck down, and on his/her lead?
I find most dog owners very careful where I walk
praying you get your confidence back very soon.
lots of hugs also
