I appreciate you taking the time to answer my question. However, no one has answered whether or not I would still be eligible for the back pay should I be found disabled but unqualified due to the recent financial changes. If you would be so kind as to address this issue, I'd appreciate it very much. Thank you.

Relying on the information available through a public forum like this and pretending it is valid "legal advice" which should control your actions is unwise. You have described issues that require the attention of a local elder law attorney. Failure to do so could be very costly for you.
