Unfortunately, what she mostly needs is money. Encourage the husband to file for unemployment anyway. Encourage them both to go down to Health and Human services and apply for TANF, Temporary Assistance to Needy Families. Some counties are far better about supplying this than others, but if they don't apply, they definitely won't get the assistance.
And don't forget about them. Check in, bring food if you can, or just stop by and talk from time to time. My husband and I were on TANF for a year and a half when I became disabled and he retrained. We live with a friend, and that helped, but being grindingly poor is a very lonely life, because some people appear to think that it is contagious. You can't "catch" poverty -- but it is endemic in this economy.
