How can I get over this terrifying experience?

Psycho therapy works wonders. See a psychiatrist, they can write meds if need be. A psychologist can not. Either way therapy will do you wonders with either one. Also, look for a support group online or in the papers - that's free and will also greatly help. His words were to frighten and control you - control is part of this psychopaths rush. Have a security alarm installed in your home, so at least there you can feel safe and sleep. Call the police station, or better yet go there from time-to-time. If you befriend an officer, you could ask him to pass by your house ever-so-often which is a great deterrent to any criminal out there (not just the man that attacked you) and that too will give you peace of mind. You have suffered a great tragedy and you do need to do the suggested first sentences, asap. Travel/walk/drive with a friend, that will help ease your fear too. These things take time and work, but you will overcome! I am so sorry this happened to you and it is normal for you to feel this way.
