First, let me state that I am so sorry you were "victimized by a predator" when you were a helpless baby. You've given no indication of your age, but please hear me when I say you need to get some professional help. Having been a victim myself (now a thriving survivor), I know how much it eats away at you inside. I know the damage predators leave in their wake.
Not only is there a spell for things like this, but there is a fantastic book! Dorothy Morrison wrote Utterly Wicked, and it's definitely a keeper in the library. I suggest you start with the Swifting of Energy Spell (page 100) and then find a nice little hex to send to your predator. The nice thing about Dorothy's book... there is no sacrifice needed.
Please let me know how you are doing and what hex you decided to use.
