Trust is still an issue

I’ve realized a sad reality, I don’t trust people, mainly men. It’s a sad thing and for the past couple days I’ve really been thinking about it. I don’t meet guys and think of he could be a nice guy. I think I wonder if he would hurt me if given the chance, I think I wonder what he is really like. It sickens me and even though I don’t consciously do it, I have realized that I do it with almost everyone.
