First off, heed the adage "Don't believe what they say" when they talk WAS speak. She may be telling you how she feels right now toward her responsibilities, but feelings can change.
I need to let her know that I am concerned for HER
Try being more validative, that will show her your concern and also change her reactions. I'll give you examples (It took me a while to figure out who was "H" and who was "M"!):
Instead of this:
H: I am just not feeling well today, well, really that's every day so...
M: Is there any way that can change?
H: No (sounding agitated). No.
Try:
H: I am just not feeling well today, well, really that's every day so...
M: Oh... I'm sorry to hear you don't feel well.
She probably can't get agitated at that response, right?
Instead of this:
H: Well, like I said, I am going to sleep for like 10 hours.
M: Ok, it's just....
H: (agitated) Yea, I KNOW...
Try:
H: Well, like I said, I am going to sleep for like 10 hours.
M: Ok, you rest up. Hope you feel better.
