Hi alm,
I'ts amazing how early in life our kids learn how to say just the right thing to get our attention. She may be angry about something that has nothing to with you, but you're there. Have you discussed your illnesses with her so that she knows how life is for you? Our kids can be very understanding and want to help us if we'll let them. Mine were pretty amazing when I finally sat them down and explained. There's more than just her anger there, there are the real reasons for it. Sit her down and talk to her about what happened, let her know that you want to help her feel better about all this. She may just need some extra attention right now.
Don't shut yourself off from her. And don't blame yourself for things that are beyond your control. If the two of you work together, my bet is that everything will be fine.
Big hugs to both of you,
Greg
