You absolutely need a family law attorney. If you are unemployed, you can file and request that your husband pay your attorney fees as well as support for you and the children while the divorce is pending.

Do NOT take the children outside of the country. If you miss court dates, he can be granted what he asks by default. It is in your best interest to remain in the US during this process.

You should have health insurance. Contact a family counselor (psychologist) to help you with your emotional distress. There are generally support groups at a family center.
