What is going on with me?

Umm..I was in a pretty abusive situation for about a year and a half. I was threatened, and my life was in danger on a few occasions, and I never felt safe. I was always on guard, and I very often felt fear and anxiety. Now I moved away from that situation, but instead of being overjoyed and emotionally free, I feel numb. I don't feel like myself anymore. I used to be very sensitive, and cry, and get emotional, and now I just feel numbness. Why am I feeling like this? Thanks for any advice.
