How can I stop being afraid men will hurt me?

Stop seeing yourself as a victim! Ted Bundy was a sociopath, but he'd have bled red like anyone else if attacked. I was always raised under a mindset of not worrying about what someone will do to you, but what you will do to them if they try it. Maybe take some self-defense cles, learn some martial arts (great for exercise and staying fit) anything you think will help you learn to walk tall.
