How to get away of this fear?

[MuriloPais]

One of my fears actually is really Weird. I have fear of passing through the bridge that is close to my home on 4 a.m with my girlfriend, after party or night , i have fear of being assaulted, somebody dangerous mess with her, i observed this fear is not to protect me, but her. At the same time i know this never happened, but idk what i would do if was 4 guys on that bridge on this hour. I should pass? I should get back to protective? This is awkward.
