Hello,
I can completely empathize with your situation, and rest assured I can certainly help you, and would be glad to do so.
During my tenure with a Big 4 Global Consultancy, I have become very aware of the Disability Rights practices in the US, and I had a friend who also got into a legal disagreement with them. This friend was also a US citizen.
I am very well equipped both research wise, and emotionally to handle your requirements. My brother is a doctor in the US and I'm sure he will give the best advice on this matter.
We can discuss more on this, perhaps on chat or through Skype, if you prefer.
Regards
Amita
