Have you checked to see if you're protected unde the Americans with Disabilities Act? If so, I thought that, by law, they are required to provide you with reasonable accommodation and are prohibited from punishing you for any real or perceived issues associated with your illness. I'm sure you've already spoken with your H.R. Department about this, so I hope they know that you're aware of your rights. Maybe there are some employment lawyers on this forum or discussion topics on the ADA and mental illnesses that can help you out with making sure your employer is following the rules.
