I am glad that you are okay and nothing bad happened. Did you call the police? They must do their job and prevent as much as possible crimes.
You don't need to be fearful person to want to live in normal society. And I hope majority of society is still normal and if other men see something wrong they will act. I act in such situations. Maybe best first go places where there are lots of people or go out with friends who escort you to your home till you get better. But I think police should be notified about such occassions even to report what car he was driving what color, everything that can help them identify this psycho.
