I am low-contact with my family, who also live in another country. I generally only reply to WhatsApp messages with responses about the weather.
At the beginning of last year, one of my children started suffering from a serious neurological illness. The issues remain ongoing. DC has required months in hospital, extensive rehabilitation and remains mostly in a wheelchair. There is no clear diagnosis or prognosis.
My DH's parents and siblings are aware, mine are not. We have kept it that way because we do not want a visit from them, or any sort of advice or help. An example of why was when I, as a teen, lost my older, married adult sister to cancer and my parents got so over-involved and overrode anything she or her husband wanted to do with her treatment, and made her illness and death all about them, rather than about my sister being able to choose how and where she wanted to die. This is not the only reason for low contact, but is a good illustration of how they are as parents.
Today, they have discovered my DC's illness and attempted serious contact. My main concern is that they are now on their way here to "help". We live in a non-English speaking country that is over 24 hours plane-ride away. I have no doubt that they will at least be considering this. How do we handle my 80ish parents unexpectedly coming to visit? If it helps, I can say no in every way possible and they would still come. They do what they want and enjoy the drama so much.
