OK, I went back and read the blog postings again.
I can answer some of the questions you posed.
If you are successful in a lawsuit for personal injuries, and your medical bills for those injuries were paid by Medicare or Medicaid, they are entitled to reimbursement for the amounts they paid and can take it out of any settlement you get in the lawsuit. Not telling Medicare or Medicaid would be FRAUD. In fact, insurance companies cannot pay a settlement to anyone who is Medicare eligible without either paying Medicare or getting a waiver from Medicare.
Medicare and Social Security issues are not within the scope of representation by your personal injury lawyer. It is a specialized field and it is never handled on a contingency fee basis. Most personal injury firms don't even handle Medicare/Medicaid/Social Security issues.
Fortunately, your attorney did verify that your bills had been paid by Medicaid, so this is really a non issue, isn't it?
"Attorney work product" is pretty similar to "attorney-client privilege". Anything the attorney prepares on behalf of his client, in anticipation of litigation, is privileged.
I don't know you, and I don't know your former friends, but the fact that they were witnesses to what happened and claim that you staged the whole thing is a huge hurdle for you. It's a huge credibility issue. Do you also realize that using their real names in your blog is not wise? You claim that they stole from you, lied, etc. If you can't prove it, you're exposing yourself to a claim for defamation.
I don't know what you're hoping to accomplish in your blog or on this board, I don't know what you hope Disney will do for you to "make it right", but it's been my experience that Disney tends to take a hard line in personal injury litigation, that everyone in the Disney organization is going to refer you to their litigation department to resolve this matter, and that you're not going to be able to circumvent that process with a blog post or some anonymous scribbling on a message board.
