I was physically and emotionally abused growing up, it didn't stop until I moved out. Even in my own apartment, it took me years before I was able to leave doors open, you know, between rooms. Until then, no matter what room I was in, every single door had to be closed and if possible locked. I never felt safe. Footsteps outside my apartment made me freak out.
That was quite a few years ago, and with time I've gotten over it. I still get scared though when I hear someone fighting, yelling, things like that. Aggression in any way. I do feel safe at home now, although I do get scared sometimes still when my husband yells at our older son, or he gets mad at something, although he's never been aggressive towards me.
I don't really have any advice, for me, time made all the difference. I hope it will for you too.
