If someone is harassing you, you can ignore them and move away from them. You can also work together with another person, ask for help from witnesses, document the situation or report the situation to an authority figure. There are organizations that offer listening and response services. They can also direct you to other resources to get the help that you need.
If you have been the victim of a criminal act, you can report it to the SPVM. Police staff can also direct you to specialized resources if needed.
