I'm glad your getting some help with this. I was diagnosed with conversion disorder and it sucks (although it sounds like it is not as bad as his). Mine is triggered by severe amounts of stress, or severe craving of SI which is probably why it feels to you like he's faking it (although I obviously don't know whether he is or not), as it is only appearing when he's stressed, even if the stress is irrational, it is still there in his mind and his mind is probably over reacting to you being stressed. It is not your fault though that his brain is irrational and throws things out of proportion. I know it's hard to not blame yourself but try to remember that he is not at fault for your mental diagnoseses (is that even a word... doesn't matter... you get the point), and you arn't at fault for his.

I hope things get better and you both will get the help you need to make it through this. Like gostryter said, I can't imagine trying to deal with someone elses problems as well as my own.

Good luck
