I'm so sorry you've been through all this, very few people could imagine what you went through with your husband and it's still very recent really, so I don't doubt it still affects you and your life in many ways.
To go through all that, which must I assume involved leaving a highly abusive relationship, takes enormous courage and fortitude. Please don't give up now.
Are you able to apply for benefits? Any help with your monthly finances will make a difference and the bank and utility companies may well give you a break on your payments to give you some breathing space while you figure out your next steps.
In terms of job hunting, without knowing your background I don't think I can give more than general advice but I've seen enough of mumsnet to know that if you reach out, career advice will be available to you. Fairly recently, careers coaches have posted in AMA and they might be able to help you right now.
Would you be able to take in a lodger to help with bills?
I'm certain others will be along with more suggestions and advice to help you out as well, and I'll keep thinking in the meantime.
You've come so far, and I understand how despairing you must be right now but you will come through this too and things will get better. Reach out to your GP for support and help and do a search for local funds that might be available to you - there are local charities that can give financial assistance during acute hardship- I'll check a link for you.
You're not alone, people here and here for you and you will come out the other side of this. Just take it one day at a time - one hour at a time if you need to.
Please also reach out to Samaritans (UK 116 123, www.samaritans.org/how-we-can-help/contact-samaritan/) or even emergency services you find yourself in the middle of a mental health crisis.
