What's wrong with me?

Why can't I trust my dad? He's never done anything but love me. My mind's been polluted by Chicken Soup stories about girls who've been sexually abused by their dads and step-dads. By my dad's not like that. I don't even want to delve into the subject, because right now I'm on the verge of tears and if I do then I'm going to cry for sure. ttyl
