Sounds like she's suffering from depression to me.
I'd be careful not to overwhelm yourself with LLs and then monitor progress against the way she feels. But maybe just keep doing what you are doing. Then listen to her concerns. The fact that she acknowledged it should be good enough. It sounds like she's admitting that it's her own issue and not yours. It almost sounds like she's letting you off the hook but if not, then be careful that she's not trying to manipulate you somehow.
If she is depressed, then you will drive yourself crazy taking ownership of it. Good luck. Sorry for a crappy answer.
