Discrimination based on perceived disability

A few weeks ago I had my first seizure ever and was admitted to the hospital. When I returned to work the following week a company owner came to my office and went into a story about how he had a family dog that had seizures. He stated that he couldn�t have a dog like that in his house and if the dog had one more seizure he would put him to sleep. He also told me a story about a housekeeper who had a seizure and that he had to fire her because he couldn�t have �one of those people� around his family.

Approximately 2 weeks later a supervisor stated that there had been ongoing issues with my work performance and attendance (despite getting a raise the month before) and that I was being offered a severance agreement or a six months probation. The timing of this meeting was very suspect in relation to my seizure and I�d had a similar conversation with threats to my employment with the same company owner when I came back to the office after surgery the prior year. I asked if I could have 24 hours to review the terms of the severance agreement. I was told that this was �not a negotiation� and I had to make a choice between the two options or lose my job. I made some changes to the agreement for my benefit without an attorney or any other witnesses present and signed the revised severance agreement.

Could this be discrimination based on a perceived disability and a covert effort to get me out of the office because of a fear that I could have a seizure at work?
