Like many others have said, I'm not sure you want to stay with that company. But it seems that if this is a diagnosed disorder and your doctor can certify that this "impacts a major life function" then the Americans with Disabilities Act may be on your side and the company would be obligated to supply "reasonable accommodations" for your disability. I briefly flirted with disability as a result of my RSI, but the rules are complex and I probably know about enough to be dangerous, but it might be worth talking to your doctor about.
