I’m still scared

Hello. I need advice. To start, I have been out and away from anything I went through that has caused me to be apart of this group. It has probably been about a year and a half now. Give or take.

I am still having nightmares almost every night about it. Nightmares that wake me up and I can’t go back to sleep because I am so scared. I also get scared and cannot look at movies/shows if someone comes on screen that even a little bit resembles him. (Dark features. Beard/hair) I just have to turn the tv off or leave the room. I am always staring at my dog and tearing up because he didn’t only mistreat me, I found out that he mistreated her as well and once I found that out, I never brought her around him again. He has changed her as well.. she still gets nervous around men with dark features. It’s much better now thankfully.

I am letting this guy live rent free in my mind and I cannot control it. I am letting this guy still scare me and I can’t control it.
