Couple of things you should consider. Contact the court about getting a child support reduction hearing/order. I believe the current minimum is $50 monthly based on your income. If you do not the support will continue to accrue, fast. This is not about trying to screw the ex or your children but just to make an acceptable temporary adjustment. When you're back on your feet, financially, they can adjust it again.
Consider bankruptcy. Not what one wants to do but what you might need to do it to get back on your feet. I did it. During my claims process, I lost a marriage, a house, and just about everything you can imagine. I lived in my vehicle. The VA doesn't care! They are an insurance company and like an insurance company, they don't want to pay. You will win, eventually, but you must never give up. This is just a test of what you are capable of doing. What doesn't kill us makes us stronger!! Never, ever, ever, ever, ever, did I say ever, give up!!!!!!!!!!!!!!!
Apply for SSDI, now.
Also, get over the idea that life is fair, cuz it ain't. Good things happen, bad things happen, both to good and bad people . . . forget fairness.
