Don't get a false sense of security. There have been good advances in the past 20 years but it's still a man's world.
Stay in contact with your friends and family and make sure to give a few of them a code word. Something like the sky is blue or I really want chinese food and they will know to call the police if you are in trouble. Do what you need to do to protect yourself. Do not count on the police. I was attacked in my home 2 hours after leaving the courthouse. I even called 911 when I got home because I was scared. They were on their way but he got there faster.
I was young and nieve and had a newborn I was thinking about. I wish someone would have told me not to go home. Please don't be nieve like I was and trust the system and that piece of paper. It's hard to imagine your home isn't safe or that someone is going to be 100x more aggressive then you have ever seen them be.
I would move and change your numbers and make sure if you work outside your home you alert EVERYONE including the receptionist and your boss/manager and security.
