I am sorry that you lost close people around you. That is hard by itself without additional stress like an accident.

The accident might not be your fault at all. What if that person was under the influence of drugs and alcohol?
Recently, my neighbor was hit by a car while he was driving a bike. it was not the driver's fault at all because my neighbor was drunk and he was driving a bike without lights during night. The driver could not see him
s.. happens ... life happens...
What? Time will be the judge.
