"I know she is working in her way and I have those days too, but part of me wants to ask what she is so burned out about. "

So why didn't you? If she says she doesn't want to talk about it then tell here you're there if she wants to talk and leave it at that. Maybe you could have even done something for her that would have SHOWN that you were there but not verbalizing it. Like offering her tea or something.

Sounds like she'd be much more receptive to those things now.
