Thanks for your update DDD. I wish I could offer advice to help ease your fears. The only point I would make is regarding SSI Benefits: at least in Wisconsin, the normal first response is Denial. It takes about a year to finally win the benefit, after several appeals, sometimes requiring legal intervention. Once benefits are awarded, however, there is a lump-sum back payment given, dating back to the original date of request.
Taking into account the documentation you must have regarding easy child/difficult children injury and current cognitive diagnosis, I can't help but think he's definately entitled to benefits. And FL may be different, but in WI, I'd tell you to get ready to be denied on first try.
And as regards fighting the court's decision....perhaps you could do some research on your State's Statutes, and draft an appeal yourself. My experience, I'm so sour on lawyers and the system, I'd try to handle this on my own. I hear what you're saying, it's such a long uphill battle.
Deb pointed out the positives, and I pray easy child/difficult child can find some clarity in his medications. No telling what miracles can occur with modern chemistry! As for his drinking, aarrrgh.
I'm with you 100% on whatever action you take. Hoping for the best, one day at a time.
Peace
