hey Dan...I am sorry to hear about your fall..
if you are ok to brake and pedal.. i think you should try a short trip... one where you feel safe, a familiar trail or road.
i still have nightmares about the van hitting me.. lol and i was just crossing(walking) on a red light..
somethings pass in time.. i know you love cycling.. so try and let that be your source of strength.
good luck.. and get better.
