It's a shame Eccles but she just isn't in the mind frame to process your information, she sounds very distraught. It would be wonderful if we could always protect our friends and make them see exactly what we see but you just can't, and particularly not when they're feeling very frail.
Plus it is true that we never know 100% what goes on behind closed doors. I hope for the best for your friend, give her time to heal a bit and be there for her, sounds like you are anyway.
