Your not alone. But they are making a case to fire you. Basically employers now seem to believe that the moment someone tells them about a disability they need to get rid of you. Perhaps because people abused it in the past. But they they are being so critical to not only build a case for non discriminatory firing but also to make you lose your cool and then they will have you. Sorry... either stop demanding your rights and do what they want or accept your about to be fired. They hold all the cards and discrimination "protection" is a joke.
