What is "wrong " with me?

A friend of mine went out with a man he didn't know. They hung out at his house, and then I get a phone call saying someone was raped. I never went out with men I didn't know, but Im assuming this has happened to a lot of women. So what makes me different than my friend?<br>Also, similar situation my brother had a friend over "to a party " and I didn't feel comfortable in my own home alone with them. When I went out for a walk they followed me. I never felt comfortable alone, why?<br><br>What is wrong with me that I always felt "wrong" about things happening around me?
