Soldier's Family in Need of Help

Hello All,
     Goodness, I'm not sure where to start. I'm a soldier in the Army, a father of six, (four girls two boys), a husband of one and a servant to many. I have been deployed to Afghanistan and Iraq. While in Iraq I hurt my back. Nothing heroic, just over use. I'm a carpenter and mason, but can no longer work in this area because of my back problems. I was getting out on a medical discharge, but, (I'm ashamed to admit), got into a little bit of trouble. My son was diagnosed with cancer two years ago when he was two months old. He lost 85% of his liver, and had so many complications due to his surgeries I can barely retell because of the emotional pain. Well, I had a hard time dealing with it all and started using alcohol as a coping mechanism. He is getting better now, as am I, (though he still eats through a tube in his stomach). However, it took getting in trouble at work to get me to admit my problems. Because of that I was reduced in rank and am making $745 less now than I was last month. They may take away my disability benifits, but I'll cross that bridge later.
     I need to get rid of my suburban before I get into trouble for non-payment. I have an old V.W. bus I am restoring that will accommodate our needs, but no funds to fix it up.
    There is alot more that this puts us in need of. My oldest daughter needs new cloaths, they all need dental work, and I wish I could give them all just a few of their wants, but I'm strugleing just to fill their needs. I'm ashamed to do so, but it looks like I'll have to go on food stamps just to feed my family. Any help, even ten bucks for a little gas, would be gratefully received. Thank you
