I agree with you that it's wrong, and I'm really sorry you're going through it. It's awful and must be so distressing.
Meds can't take it away, you're right, but - as my doc said to me when I made a similar comment to the one you have - they were aiming to try and take the edge off so that I could get through it and start rebuilding. It was about providing as much support in as many ways as they could.
The suggestion above on a second legal opinion is a good one, even if it's just to give you more of a sense of control and being armed with information. Sometimes it's helpful just to hear things explained in a different way by somebody with a different perspective and way of articulating ideas.
I understand why you feel like your whole life is ruined, but I don't think it will always feel like that. I don't think your whole life is ruined anyway, but I bet he wants you to believe that. To me, his decision to do this shows that he felt you were doing too well and he's trying to get control back.
Did you have any support previously for the abuse? From Women's Aid or attending the Freedom Programme? Specific counselling? Online forums for survivors?
I ask because some of the women I met on Freedom were going through the kinds of things you describe, and it seemed to really help them. It's not therapy, but it would give you a couple of hours a week in a room with women who understand what you're going through and went through, and who won't judge you or blame you. It might also help you feel differently about your future.
Also, Freedom don't keep records of who's attended the groups specifically to stop men like your ex using it to harass, abuse, control etc. My group just used to do a first name only sign in page each week in case of a fire, and that was destroyed afterwards. Nobody in the building except the facilitators knew who we were or why we were there, and the times and locations aren't advertised or made public. (You have to contact them to get a place - details on their website www.freedom programme.co.uk). Often they're in places with a crèche or at children's centres, so it looks like just women attending a group for mums or a craft group or coffee morning or something else completely innocuous.
I know Women's Aid can offer counselling, and I'm aware there are areas of the country where the NHS has started running therapy specifically for women who've experienced domestic abuse. Either way, being able to have some form of trauma therapy with a therapist who understands domestic abuse could really help you cope with this, cope with the wreckage, and build some hope up for you.
He can't sue you for going to the doctor's or having counselling. Your medical records are confidential, and having medical needs is not something you can be sued for. Has he specifically threatened to do that? Or just generally if you tell anyone?
There's also Samaritans. You can email on [email protected] or phone on 116123. They can't even identify who you are, so you can tell them absolutely anything, any time you need to talk and get it off your chest. You don't have to be feeling suicidal to call them, although if you are they are kind and won't judge you. You could also create a new email address to contact them if it made you feel safer (although when they respond to you the person writing the email can't see your address anyway).
There are also survivor groups on Twitter. You could create an entirely anonymous account and use it to connect with other people, or just vent, or however you wanted to. I know there's an #abusetalk chat on Wednesday evenings you could look in on. It has a different topic each week. There will be others, depending on what helps you.
There are loads of books out there that might help. Based on some of the things you've described him doing, there is one that comes to mind called Treating PTSD in Battered Women (Edward Kubany - it's American, hence the uncomfortable title), but it covers healing from the ways they put poison in your mind with all the put downs etc. It's described as a handbook for therapists, but I've used parts of it on my own - it contains hand outs and things to give to clients/patients. Hardback is stupidly expensive, but Kindle is £25. (Might be something for after September though depending on the level of scrutiny of your purchases? But downloading a free sample wouldn't hurt. If you don't have a kindle you can download the kindle app to read it that way.)
There are probably other (less expensive) books I could recommend as possibilities for you to look at, but I won't unless you want them.
I don't expect you to go off and do all these things, I'm just sharing things that have helped me or people I know. Take the parts that are helpful to you. You don't have to be alone with all this.
Again, I'm really sorry you're going through this. I hope you are able to find something to help you get through the next few months. Take care
