Hi GF!!!!! It is good to see you, although I am so sorry to read about the reason you've come back to visit.
I think if she is in your house, you will be able to make a few observations that will help answer any questions you have about "is she or isn't she". Your example of getting help is going to be her best hope. If you observe "proof" in your presence, then it might be good to have a kind and non-judgmental talk with her. Unfortunately, she just may not be ready to hear it. You will all be in my prayers!
