My husband and I are without family except for our daughter who is 41 yrs old. She has estranged herself from us. We are really nice people, really we are. We were not abusive to her in any way, but she says she is done with us. We are 72 and 85. Husband has been unwell most of 2020. I told her in a letter that we could use some moral support and I told her how old we are. She replied that she knows how old we are. That I was trying to make her feel guilty. No word from her since then. She has blocked us on social media and the phone. We are not asking her to come to our town and take care of us. All I ask is a Christmas card and mothers/fathers day card. Maybe she could call us and inquire how we are faring during the virus, but nothing from her... Do you think there is any hope here with her? What should I do about this matter?
PS she is a professional in the health field.
