I was lucky to be able to move 2100 miles away when I left but I sure understand your feeling because after my mom died & the trauma I experienced with the home care person & the police I was having massive depersonalization experiences there. They hit a few times after moving but decreased as I realized I was safe away from everyone. Only then I was able to feel safe in my new environment. That option is not possible for most. I do understand your issues & it does take time to build up the confidence that you can handle encounters if they occur. Shoot, I went back to Ca 11 years after I left for a court case against him & I was staying at the ranch where my horse still was & he was doing nightly feedings. I was so anxious that my anger would flare up again after all the therapy work I had done to process & heal from all those years in the bad marriage. Your response is normal, time & healing & learning you can handle it will help
