I've never wanted to harm my baby..

The thought of harming my baby has NEVER crossed my mind, ever! But I have this recurring fear that someone or something else will. Like something as little as someone accidentally knocking my baby out of her stroller to someone suddenly abducting her and hurting her. I feel so paranoid when I'm out in public with my baby but I can never shake the fear of someone possibly harming my baby.. should I talk to someone or will this fade?
