I seem to keep saying this to women in your situation @EndOfMyPip but really, really, REALLY think about getting yourself on the list for council housing. I did, despite being told I had no chance of getting anywhere - and it honestly didn't seem as though I did at times (94th in line for one place). But I did get a place for me & DC in less than two months and I'm so happy here. It was an utter miracle that I got it, but I did.
You won't lose anything by applying, but you might just get that place that tides you over for a little while until you can build up funds again. I'm in a smallish city, but my weekly rent for a 3 bed maisonette is around £90, and I didn't have to pay a deposit. The same maisonettes on my floor rent for over £800 a month when let privately.
As for work, I was completely unemployable, thanks to various mental health issues & employment history (I was the boss, so there wasn't anyone who could give me a reference). I built myself back up with volunteering for various projects. Now I have at least four fairly well-recognised people in their field who'd vouch for me if I ever feel able to work again. It'd be completely at odds with what I did for a living before, but I have the experience certain organisations would want. Volunteering doesn't pay the bills, but it does show your skills, & give you contacts. Not just that, but it's given me the best friends I've ever had, who supported me enormously.
Another thing I'd suggest is seeing if you have a local domestic abuse charity. This relationship is abusive, no doubt about it. Making contact with them may help strengthen your resolve, as well as them being able to provide you with more relevant local information. In my case, they were brilliant advocates for me, as well as just meeting me for coffee and a chat, which really helped.
Also, your husband sounds like a complete ingrown pube,with added pus of infection. You can get out of this. It won't be fun, but you can, and rediscover what it is to be happy again. I promise you that.
