Yes, please do get a lawyer. You sound like you may have a very good case. Under the Americans with Disabilities Act and their 2009 amendments, the ADAAA, the focus now is on the Employer's conduct not on the extent of your disability. You may have relief under state law as well. You would be best served by consulting a Nevada employment lawyer. Before you go to court, you need to file an administrative case. As there are time limits to filing an administrative case, you should consult immediately.
