A lawyer will need to know much more information in order to assess your matter for litigation. See www.nela.org as a reference to look for attorneys who may be able to assist you.
I cannot make any commitment to represent you; however, I will consider it if you send me a copy of the documents you filed to support your disability discrimination and retaliation claims, and the determination in your matter.
NELA is an organization of labor and employment attorneys that are dedicated to representing generally Plaintiffs in such matters.

To the extent that the employer states that you were terminated on account of its inability to accommodate you, when the accommodation was sufficient for the previous eight years, that suggests that there could be a real problem with the employer's explanation. You should definitely contact counsel to try to get represented. Your time limit will expire quickly now that you have already received a right to sue letter.
