I would contact your creditors and explain your situation as well as contacting an attorney. Check with county offices and maybe even social services and see if they can refer attorneys who do pro bono work. Good luck with everything.
You're right: you do need help. You need to talk to a family law attorney immediately. An experienced attorney from your state will be able to give you advice that's in your best interest.
In the mean time, gather any bank statements, tax documents, or credit card / mortgage paperwork so that you're organized when you talk to an attorney. If your husband is being agressive or violent at all, please protect yourself. Keep a record of any inappropriate interactions you have so you're prepared to give the details.
I'm so sorry you're going through this. Stay strong, and best of luck to you!
