Hello, and Welcome Justlost
Have you found somewhere to go to be safe tonight? I do hope so, and feel you for your situation so much.
You can call the National Domestic Helpline 24/7 I believe, and they can direct you to services to support you. The chat line on here (detailed under Support & Advice on here), can also direct you to refuge services and services generally in your area.
I hope someone is taking care of you and your children tonight, my thoughts are with you.
do let us know whatever you might need to see if anyone can help.
warmest wishes
