Yeah, Dave this sounds bad, but you have skills it sounds like. Can you ask the law firm to go full time? If your kids are old enough, maybe they can work part time or full time?!?! What about trying temp agencies for accounting work? At this point, take what you can get. Also, if you apply out of state, maybe it's time for a move, if you get the job?!?!
I will never forget what a teacher told me, "God will provide where he wants you to be." I obviously just know a fraction of what your going through, so please understand I'm trying to help with possible solutions. I would also recommend asking your church friends, if they can help out with your job search. Your friends are usually your best referral for finding work. The old saying, it's not what you know, but who you know.
