Take steps to prepare yourself should any type of attack ever happen. Take some self defense classes and read up on what attackers look for in targets. For example, there was a survey done in prisons by rapists and they said that they look for women who wear their hair up (easy to grab) and wear loose clothing (easy to remove), are distracted by something (cell phone), are in solitude, and avoid women with objects they could defend themselves with (umbrella was mentioned a lot), heels (pointy). Keep pepper spray with you.It's possible something happened to you in your past that is triggering these fears, or it could be all in your head. Either way, learn to defend yourself and you will feel a lot safer (this worked for me.)
