Advice for possible PTSD after Domestic Abuse

Hi, I’m wondering if anyone has any advice or has had experience where they felt they had PTSD after an abusive relationship ended and almost 3 years on from the end of your relationship. For a while I was fine, had pulled myself together and felt like I was finally getting my old self back. Most of my strength came from my daughter and wanting to keep going for her. I also had a lot of family support, went to groups with other women and my new partner. But in the last few months my ex husband has been messing me around, playing with my head again and messing with my daughter. Not turning up to contact. Not paying child support. Since we separated I have never really had the confidence to even go to my local store for food shopping Or I will drive miles away from where I live to get the shopping and petrol because I don’t want to run into him or his family. We have been trying to move for a very long time but seem to come across so many road blocks with this. So I’m quite isolated really being around where him and his family live. It’s also where I grew up and all my support is so quite worried about moving too far away from them too. But anyways, recently he has been contacting a lot. A mixture of nice messages and nasty messages. Mainly when he can’t get his own way. I have been having nightmares now for months. I wake up in sweats. Sometimes crying. I go back to sleep and seem to end up in the same dream again. I’m also very vigilant of wherever I go. Looking over my shoulder. Waiting In the car for 5 minutes before il get out to scout and make sure that no one is around to create a confrontation in front of my daughter. I hate being at home incase one of them turns up at the door again. Iv been to the dr, who doesn’t seem to really have time for my situation. I meditate a lot. But lately can’t seem to concentrate enough. It’s just a frustrating experience. I am also 29 weeks pregnant, so obviously hormonal, but taking citalopram too for my anxiety. I just don’t know where to turn to get the right support for this. Any suggestions would be greatly appreciated.
