Hope you are alright bud! Can totally understand what your going through, ive had a slightly similar incident, a man walked out in front of me when i was driving a bus, he never even looked and i had no time to stop and i hit him. Thankfully his injuries were only minor and i was found not at fault at all, but its the single worst thing ive ever experienced. The best thing to do is get back on the road as soon as you can and get your confidence back bud! I hope everything turns out ok for you.
