Hi, it sounds like a really difficult time for you but there's no "just" in living with the torment of it, and no "just" in being "mentally abusive". Those, let alone the history of violence, are (obviously!) going to have a major impact on you.
Do you think it might help if you started documenting all the things you're going through to pass on to Social Services and maybe if you had someone with you, in your corner to go with you and push things a bit? That's if you haven't already tried that of course.
It must have felt like they were making you a victim all over again though with their response to you, almost like adding "insult to injury". And I'm really sorry that you had to go through all of that.
Just a long shot though, were all of the places "in the system" that you tried? Sometimes charities or voluntary organizations can be really helpful, and they will have people working for them JUST/SOLELY because they want to help make a diffeence in peoples lives. And maybe at least some of the hotlines can offer you emotional support if not practical because it sounds like you can do with all the support you can get.
Sorry if you've been there/done that before though, just some thoughts. Really want to help.
If you want to talk about things more though I'm more than happy to be here for you, to offer advise, encouragement, suggestions, an ear, support, understanding........whatever I can do.
