ZenZeta,
I understand you questioning about saying the diagnosis to your boss. I would also doubt it. In an ideal world, talking straight to your boss would be the best and you could be much more comfortable if (s)he understands but I’m not sure whether people in general is ready.
From what you describe, your participation is more than enough.

On my second year of working as a teacher I found a very understanding principal and I dared to tell him. It ended it up being so helpful and liberating. So much that I ended it up being friend with him and my other coworkers.

How do you see her or him in this sense?
